Volume of Cylinders and Cones

Volume

- Volume is the amount of three -dimensional space occupied
by an object. Volume can also be referred to as capacity.

Volume of
Cylinders

-To find the volume of a cylinder, multiply the area of the base
by the height of the cylinder.

-The base of a cylinder is always a circle , so the find the area
of the base, use the formula πr²

Find the volume of each cylinder. Round your answers to
the nearest hundredth.

Use what you learned about the volume of cylinders to
answer the question below.

7. The area of the base of a cylinder is 150 square inches. If the volume of the
cylinder is 1,050in3, what is the height of the cylinder?

Volume of Cones

Examples 1 and 2 below show a cylinder and a cone with the same height
and radius, as well as their volumes. Observe the examples and answer the
questions that follow.

Volume of

Cones

-The volume of a cone will always be 1/3 the volume of a cylinder
with the same height and radius.

- The formula for the volume of a cone is V=1/3Bh , or V= Bh/3 .

-Since the base of a cone is a circle, the area of the base, B, is
found using πr²

Find the volume of each cone. Round your answers to the
nearest hundredth.
