Question

Find the volume of the cylinder to the nearest cubic foot. Use a calculator.



A. 236 ft3

B. 942 ft3

C. 75 ft3

D. 251 ft3

Answer 1

Although a cylinder is technically not a prism, it shares many of the properties of a prism. Like prisms, the volume is found by multiplying the area of one end of the cylinder (base) by its height.

Since the end (base) of a cylinder is a circle, the area of that circle is given by

area = πr^2

Multiplying by the height h we get volume = πr^2, where:
π is Pi, approximately 3.142
r is the radius of the circular end of the cylinder
h height of the cylinder

Answer 2

Someone notified me that I missed a part of my volume equation. Here's the fixed one:
