Question

A cylinder is 5 centimeters tall and has a radius of 2.1 centimeters. Find the volume to the nearest tenth. Use 3.14 for .

61.2 cm
33.0 cm
65.9 cm
69.2 cm

Answer 1

Option D

Explanation:

Volume of a cylinder is
`V=\pi r^2h`

h - height

r - radius

We are given the radius of 2.1 centimeters and the height of 5 centimeters.

Using 3.14 for pi:

`V=3.14*2.1^2*5\\\\V =69.237`

69.237 ≈ 69.2

Option D should be the correct answer.
