Question

4. What is the volume of the cylinder? Express answer in terms of a (hold and

press option and the letter p together).
10 mm-
B = 4 mm2

Answer 1

Given:

Base area = 4π mm²

Height = 10 mm

To find:

The volume of the cylinder.

Solution:

Base of the cylinder is circle.

Area of the base = πr²

πr² = 4π

Volume of the cylinder = πr²h

Substitute 4π in place of πr².

= 4π × 10

= 40π mm³

The volume of the cylinder is 40π mm³.
