Exercise 25 Page 603

Use the formula for the volume of a cone.

Approximately 4.5m

Practice makes perfect

We are given that the volume of a cone is 42.39 cubic meters and the radius of the base is 3 meters.

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 3 meters. The volume is 42.39 cubic meters. Let's substitute these values into the formula and solve for the height h.

V=1/3π r^2 h

SubstituteII

V= 42.39, r= 3

42.39=1/3π ( 3)^2 h
