the cylindrical part of an architectural column has a height of 305 cm and a diameter of 30 cm find the volume of the cylindrical part of the column.use 3.14 for pi and round youre answer to the nearest cubic centimete if needed.​

Answers

Answer 1

Radius(r)= 25 cm = 25/100= 0.25 m
[1 cm = 1/100m]
Height (h)= 3.5 m
Curved surface area of Cylinder= 2πrh
= 2× (22/7) × 0.25 × 3.5
= 2× 22× 0.25 × 0.5
= 2× 0.5 ×22× 0.25
= 1 ×22× 0.25
= 5.5 m²
Curved surface area of 1 Cylindrical column= 5.5 m²
Curved surface area of 10 Cylindrical column= 5.5 × 10= 55 m²
Rate for painting 1 m² of the cylindrical column = ₹ 15.50
Cost of painting 10 cylindrical columns= 55 × 15.50 = ₹ 852.5.

6. Find all missing angles m<1 m<2 m<3​

Answers

Answer:

1. 128

2. 52

3. 47

4. 133

5. 81

Step-by-step explanation:

1. <1 and <52 are same side interior angles, therefore supplementary. So they should add up to equal 180, this means that <1 is 180 - 52. Solve to get <1 is 128

2. <2 is an alternate interior angle to <52, this means that they are congruent. Since they are congruent, they have the same value of 52.

3. <3 is an alternate interior angle to <47, so they are congruent, this means that they both have a value of 47

4. <4 is supplementary to <3 so you can say that <4 is equal to 180 - 47. Solve this to get <4 is 133

5. <5, <52, and <47 are supplementary when you combine all three. So you can create an equation that says <5 is equal to 180 - 52 + 47. This gives you that angle 5 is 81.

Any help is appreciated!

Pythagorean Theorem:

625=576+x^2

49=x^2

x=sqrt49

x=7

Hope this helps!

Merry Christmas!

Answer:

By using the Pythagorean theorem we can solve this

The Pythagorean theorem states that [tex]c^2=a^2+b^2[/tex] where c is the hypotenuse (longest side of the right triangle) and a and b are the other 2 sides. LEts use x to represent the missing side

Therefore,

[tex]25^2=24^2+x^2[/tex]

[tex]625=576+x^2[/tex]

[tex]625-576=576-576+x^2[/tex]
