Question

A cylinder has a height of 23 m and a volume of 18,488 m³. what is the radius of the cylinder? round your answer to the nearest whole number. responses 256 m 256 m 50 m 50 m 32 m 32 m 16 m

Answer 1

Explanation:

The volume for a right cylinder is

`V=\pi r^2h`

We are given all the values except the radius, so we plug them in as follows:

`18488=\pi r^2(23)`

Begin by dividing by 23π to get

255.8657603 = r²

and then take the square root of both sides to find that

r = 15.995 or 16 m
