Question

What is the approximate volume of a cylinder with a diameter of 14 meters and a height of 10 meters? Use 3.14 for pi.

A.
219.8 m3

B.
439.6 m3

C.
1538.6 m3 ( I think this one)

D.
6154.4 m3

Answer 1

Vol Cylinder = Pi r^2 x the length

Dia = 14 so radius = 7

Therefore Vol = Pi x 7^2 x 10
= 3.14 x 49 x 10
= 3.14 x 490
Approx 3 x 500 = 1500

Answer 2

V = pi * r^2 * h

V = 3.14 * 7^2 * 10

Simplify exponent:

V = 3.14 * 49 * 10

Multiply:

V = 1538.6

Your answer is correct :)
