Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.

Answer:
1. 660.52
2. 572.56
3. 283.53
4.254.47
5. 63.62
6. 380.13
Step-by-step explanation:
do πr²
r = radius
if you have a diameter like question 4 divide by 2 and you get radius
Answer:
1. A = 660.52 square units. C = 91.11 units.
2. A = 572.56 square units. C = 84.82 units.
3. A = 283.53 square units. C = 59.69 units.
4. A = 254.47 square units. C = 56.55 units.
5. A = 63.62 square units. C = 28.27 units.
6. A = 380.13 square units. C = 69.12 units.
Step-by-step explanation:
The equations for Area and Circumference of a circle are as follows:
A = πr², where r is the radius.C = 2πr, where r is the radius.You are given the radius (or diameter) of each circle which can be substituted into the above equations for r. Diameter is the entire length across the circle through the center, which is equal to 2(r).
1. A = π(14.5)² = 660.5198. The area is approx. 660.52 square units.
C = 2π(14.5) = 91.106. The circumference is approx. 91.11 units.
2. A = π(13.5)² = 572.555. The area is approx. 572.56 square units.
C = 2π(13.5) = 84.823. The circumference is approx. 84.82 units.
3. A = π(9.5)² = 283.528. The area is approx. 283.53 square units.
C = 2π(9.5) = 59.690. The circumference is approx. 59.69 units.
4. Diameter = 18; 18/2 = 9 = r. So, A = π(9)² = 254.469. The area is approx. 254.47 square units.
C = 2π(9) = 56.548. The circumference is approx. 56.55 units.
5. r = 9/2 = 4.5. So, A = π(4.5)² = 63.617. The area is approx. 63.62 square units.
C = 2π(4.5) = 28.274. The circumference is approx. 28.27 units.
6. A = π(11)² = 380.132. The area is approx. 380.13 square units.
C = 2π(11) = 69.115. The circumference is approx. 69.12 units.

Answer:
1372 cubic ft.
Step-by-step explanation:
[tex]V=\frac{4}{3} \pi 7^3[/tex]
[tex]V=\frac{4}{3} \pi 343[/tex]
[tex]V=457\frac{1}{3} \pi[/tex]
Since pi is 3 to find the approximate answer, do:
[tex]V=457\frac{1}{3} (3)[/tex]
[tex]V=1372[/tex]
Hence, the volume of the sphere is approximately 1372 cubic ft.
Answer:
V = 1,372 ft³
Step-by-step explanation:
You have been given the equation necessary for calculating the volume of a sphere:
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.
radius = diameter / 2
radius = 14 ft / 2
radius = 7 ft
Now, you can plug this value into the formula and simplify to find the volume.
[tex]V = \frac{4}{3}\pi r^{3}[/tex] <----- Volume formula
[tex]V = \frac{4}{3} * (3) *r^{3}[/tex] <----- Plug 3 in for "π"
[tex]V = \frac{4}{3} * (3) * 7^{3}[/tex] <----- Plug 7 in for "r"
[tex]V = \frac{4}{3} * (3) * (343)[/tex] <----- Solve 7³
[tex]V = 1,372 ft^{3}[/tex] <----- Multiply all the terms together

Convert the mixed numbers to improper fractions, then find the LCD and combine.
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple (LCM) of the denominators. This number is same as the least common denominator (LCD).You can then write each term as an equivalent fraction with the same LCD denominator.Hopefully this helps you! ^^

-You cant really see what 1 says but it says (The net below can be folded to make the triangular prism? Label the dimensions of the prism.)
And 8 says (Calculate the total area of the net and the surface area of the triangular prism from Problem 7. area net= surface area= ___ cm^2)
Answer:
1. Left side = 3 inches, Bottom side = 4 inches, Right side = 2 inches, Top side = 5 inches
2. A = 6 inches²
3. A = 8 inches²
4. A = 10 inches²
5. A = 12 inches²
6. A = 36 inches²
7. Left side = 5 cm, Bottom side = 12 cm, Right side = 4 cm, Top side = 13 cm
8. A = 180 cm²
Step-by-step explanation:
1. Label the dimensions of the prism:
Left side = 3 inches
Bottom side = 4 inches
Right side = 2 inches
Top side = 5 inches
2. Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 3 x 2
A = 6 inches²
3. Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 4 x 2
A = 8 inches²
4. Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 2
A = 10 inches²
5. (They gave the formula of the two triangles, but the question said green rectangle? They must've meant yellow triangles)
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 3 x 4)
A = 2(1/2 12)
A = 2(6)
A = 12 inches²
6. Total surface area of the triangular prism:
Formula:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 6 inches² + 8 inches² + 10 inches² + 12 inches²
A = 36 inches²
7. Label the dimensions of the prism:
Left side = 5 cm
Bottom side = 12 cm
Right side = 4 cm
Top side = 13 cm
8. Total surface area of the triangular prism:
First, we can find the area of each shape, as we had previously to find the total area of the net and the surface area of the triangular prism.
Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 4
A = 20 cm²
Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 12 x 4
A = 48 cm²
Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 13 x 4
A = 52 cm²
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 5 x 12)
A = 2(1/2 60)
A = 2(30)
A = 60 cm²
Total surface area of the triangular prism:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 20 cm² + 48 cm² + 52 cm² + 60 cm²
A = 180 cm²

Answer:
Let [tex]\pi[/tex] represent 3.14
SA = 2[tex]\pi[/tex]r^2 + 2[tex]\pi[/tex]rh
SA = 2[tex]\pi[/tex](5)^2 + 2[tex]\pi[/tex](5)(12)
SA = 2[tex]\pi[/tex](25) + 2[tex]\pi[/tex](60)
SA = 50[tex]\pi[/tex] + 120[tex]\pi[/tex]
SA = 50(3.14) + 120(3.14)
SA = 157 + 376.8
SA = 533.8inch^2
Therefore the surface area of the cylinder is 533.8 square inches.
Answer: Let represent 3.14SA = 2r^2 + 2rhSA = 2(5)^2 + 2(5)(12)SA = 2(25) + 2(60)SA = 50 + 120SA = 50(3.14) + 120(3.14)SA = 157 + 376.8SA = 533.8inch^2

A party hat has a height of 7 inches and a diameter of 6 inches. What is the volume of the party hat in cubic inches? Use 3.14 for pie.
Answer:
65.94 in³
Step-by-step explanation:
First, we need to determine to the shape, a party hat is a cone.
The volume formula that use to calculate the cone is 1/3hπr².
Notice: h is for height and r is for radius
Using this formula, we can easily set up the equation below:
1/3 · 7 · 3.14 · (6/2)² = 65.94 (cubic inches)
You must halved the diameter first (in this case, 6) and then square it.
So: The answer of this question is 65.94 in³
