Question

What is the volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft?

Use 3.14 for pi and round only your final answer to the nearest hundredth.

I don't even really need the answer. If someone could explain to me how to do it, that would be great! I looked up what I was supposed to do and got a coupe different answers. 

Answer 1

5889.95

Explanation:

volume of a cylinder is the area of the base times the height. To find the area of the base it is
`a=\pi r^(2)` Since they give diameter you need to find radius by dividing. 17.5 divided by 2 is 8.75. the area is
`76.5625\pi` then times height it is
`1875.78125\pi` then, like they said, use 3.14 as pi. Round to get 5889.95

Answer 2

The volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft is:

5889.95 ft³

Explanation:

We are given a base diameter of a right circular cylinder as :

d = 17.5 ft.

hence radius of cylinder i.e. r =d/2 = 8.75 ft.

height of the cylinder = 24.5 ft.

now we know that volume of cylinder i.e. V is given by :

V = πr²h

putting the value of r and h in the given formula to obtain the volume

V = 3.14×(8.75)²×24.5

= 5889.95 ft³

hence, the volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft is:

5889.95 ft³
