Question

A cylinder has a base diameter of 20 meters and a height of 5 meters. What is its

volume in cubic meters, to the nearest tenths place?

Answer 1

The answer is 1570.8

Answer 2

Volume = PI x r^2 x h

r -s 1/2 the diameter ( 20/2 = 10)

Volume = 3.14 x 10^2 x 5

Volume = 3.14 x 100 x 5

Volume = 3.14 x 500

Volume = 1570 cubic meters
