Exercise 26 Page 603

Use the formula for the volume of a cone.

Approximately 8.0in.

Practice makes perfect

We are given that the volume of a cone is 1205.76 cubic inches and the radius of the base is 12 inches.

To find the height, we can use the formula for the volume of a cone. V= 13π r^2 h Here, r is the radius and h is the height of the cone. We are given that the radius of the cone is 12 inches. The volume is 1205.76 cubic inches. Let's substitute these values into the formula and solve for the height h.

V=1/3π r^2 h

SubstituteII

V= 1205.76, r= 12

1205.76=1/3π ( 12)^2 h
