Question

A cylinder has a base diameter of 4cm and a height of 2cm. What is its volume in cubic cm, to the nearest tenths place?

Answer 1

Answer: 25.1 cm'3

Explanation:

h = 2 and d =4 and r= 2 (the radius is half of the diameter)

v = πr 2h

v + π(2)'2(2)

v = 25.132741228718

v = 25.1 cm '3

Answer 2

Answer: 25.12

Explanation:

Formula for Volume of Cylinder - π x r² x h

First you want to find the area of the base.

π x 2² x 2

3.14 x 2² x 2

= 25.12
