Step 3 Multiply the area of the base by the height of the solid.

Example 2 Find the volume of a cylinder that has a base with a radius of 12.0 cm, and a height of 21.0 cm.

Step 1 You know that the base is a circle, and the area of a circle is the square of the radius times ^,and the volume is the area of the base times the height.

Step 2 Find the area of the base.

Step 3 Multiply the area of the base by the height of the solid.

The volume is 9490 cm3.

Example 3 Find the volume of a cylinder that has a diameter of 15 mm and a height of 4.8 mm.

Step 1 You know that the base is a circle with an area equal to the square of the radius times ^.The radius is one-half the diameter. The volume is the area of the base times the height.
