Find the volume of a cylinder having a radius of 5 cm and a height

of 12 cm.

of 12 cm.

Given:

r = 5 cm; h = 12 cm

The formula:

V = Π r2h

V = (3.14)(52)(12)

V = (3.14)(25)(12)

V = 942 cubic cm!

r = 5 cm; h = 12 cm

The formula:

V = Π r2h

V = (3.14)(52)(12)

V = (3.14)(25)(12)

V = 942 cubic cm!

the area of its circular base by its height.

example:

cylinder

This cylinder has a height of 15 cm and a

diameter of 8 cm.

diameter of 8 cm.

Its radius equals 4 cm.

Area = 3.14 x 4 x 4

= 50.24 x 15cm =

Area = 3.14 x 4 x 4

= 50.24 x 15cm =

To find this cylinder's volume, multiply

the area of the circle by the height.

the area of the circle by the height.

pi x square of the radius x height
