Exercise 9 Page 431

Use the formula for the volume of a cylinder.

50π cubic units

Practice makes perfect

The volume of a cylinder with the base B and height h can be calculated by the following formula. V=Bh Since we are given both the base and height of the cylinder, we can substitute them into the formula and calculate V.

V=Bh

B= 25π, h= 2

V=( 25π)( 2)

Multiply

V=50π

The volume of the cylinder is 50π cubic units.
