the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field
Radius = 35 m
Step-by-step explanation:Given:Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.
To Find:What is the radius of the circular field ?
Solution:Let the radius of circular field be r metre.
Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.
★ Circumference = Total cost/Cost per metre ★➯ Circumference = 2640/12
➯ 220 m
As we know that , formula of circumference is
★ Circumference = 2πr ★
⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = rHence, the radius of circular field is 35 metre.
Answer:
Solution given:
total cost =Rs 2640
rate=Rs 12/metre
We have
circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]
2πr=220m
r=[tex] \frac{220}{2π} [/tex]=35.01
r=35m(approximately)
the radius of the field is 35m.
Given that a = 14 cm and b = 25 cm, work out the area of the triangle.
Answer:
175
Step-by-step explanation:
I am assuming that you mean that a and b are both bases of a right triangle. Please correct me if I am wrong.
14 * 25/2 = 350/2 = 175
The area would then be 175 cm²

What is the volume of the sphere with a diameter of 18 centimeters? Round to the nearest
hundredth.
Answer:
3054.024cm^3
Step-by-step explanation:
Given data
Diameter= 18cm
Radius= 9cm
The expression for the volume of a sphere is given as
Volume = 4/3πr^3
Volume= 4/3*3.142*9^3
Volume= 4/3*3.142*729
Volume= 9162.072/3
Volume= 3054.024 cm^3
Hence the volume is 3054.024cm^3

Simplify this expression using the distributive property.
2(2z+9)
Answer:
[tex]\bold{4z+18}[/tex]
Step-by-step explanation:
Hi there!
The Distributive Property states that
[tex]\bold{a(b+c)=ab+ac}[/tex]
Now, let's use this property to solve our problem:
[tex]\bold{2(2z+9)}[/tex]
[tex]\bold{4z+18}[/tex]

In order to simplify this, we're going to use a property that's called the Distributive Property:
[tex]\longrightarrow\tt{a(b+c)=ab+ac}[/tex]
Where a, b, and c can be variables, constants, or both (like 4c).
Now let's simplify our expression:
[tex]\longrightarrow\tt{2(2z+9)}[/tex]
Multiply 2 times 2z and 9:
[tex]\longrightarrow\tt{4z+18}[/tex]
Hence, we conclude that the answer is: [tex]\tt{4z+18}[/tex].
I hope this helps you! Have an awesome day.

Q19. Look at the image.
Answer:
It's C
Step-by-step explanation:
Because if you look at the other numbers they all add up to the next number by 4. 4+4=8 8+4=12 12+4=16 16+4=20 20+4=24
Therefore, x intercept is 24 and y intercept is 18. Hope this is correct if it's not correct then I'm very sorry. Have a nice day. ;)

A marble is picked at random. Without putting the first marble back, a second marble is picked at random. Find the probability that first marble picked is green and second marble picked is red. Write your result as a percentage.
Answer:
Probability = 1/5 = 20%
Step-by-step explanation:
Prob (1st marble green) = Green Marbles / Total Marbles = 3/6 = 1/2
Pr (2nd marble red), without replacement = Red Marbles / Left Total Marbles = 2/5
Prob (1st marble green, & 2nd marble red) = 1/2 x 2/5 = 1/5
Prob in percent = 1/5 x 100 = 20%
Find the sum of the first 10 terms for the following sequence: a = {-1, 2, 5, ... }

Find the area of the following colored colored regions?
Answer:
64-16pi(not rounded)
64-50.27 = 13.73 (rounded)
Step-by-step explanation:
Square = side^2 - side =8 (4+4)
8*8 = 64
Circle area= pi r^2
16 pi = 50.27
Square-pi*r^2 = answer
64-16pi(not rounded)
64-50.27 = 13.73 (rounded)

A. One Solution
B. Infinitely Many Solutions
C. No Solutions
Answer:
C. no solutions
Step-by-step explanation:
Both equations have a slope of -2, but have different y-intercepts. Therefore, the graphs of the equations are parallel, but don't coincide, nor do they intersect. So, there are no solutions
Jane is buying a jacket that regularly costs $54. However, the jacket is on sale for 25% off the regular price. A sales tax of 6% will be added to the final purchase price. How much will Jane pay for the jacket, including tax?
Answer:
42.93
Step-by-step explanation:
54 x 0.25 = 13.50
