Exercise 17 Page 603

Use the formula for the volume of a cone.

Approximately 398.2 m^3

Practice makes perfect

Consider the given cone.

To find the volume, 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 told that the height of the cone is 9 meters. The radius of the base is 6.5 meters. Let's substitute these values into the formula and calculate the volume.

V=1/3π r^2 h

SubstituteII

r= 6.5, h= 9

V=1/3π ( 6.5)^2 ( 9)
