Question

What is the approximate volume of a cylinder with a diameter of 28 ft and height of 20 ft? Use 3.14 to approximate π , round to the nearest tenth.

Answer 1

The answer is V= 12315.04

Volume of cylinder is V=πr2h

Radius is 14, 28/2 =14

Plug into the equation,

π(14)^2 (20)

14^2 = 196(20) = 3920

3920*3.14(pi) = 12315.04
