Question

A cylinder has a base diameter of 18 feet and height of 15 feet . What is it’s volume in a cubic feet to the nearest tenths place ?

Answer 1

v = pi * r^2 * h

radius is half of diameter so 18/2 = 9. now plug that in :)

v = pi * 9^2 * 15
v = pi * (81)(15)
v = 1215(pi)
v = 3817.0

hope this helped :)

Answer 2

it's 3817.04 but you round to the nearest tenth
