Exercise 8 Page 866

Use the formula for the volume of a cylinder.

665 in^3

Practice makes perfect

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h Since we are given both the radius and height of the cylinder, we can substitute them into the formula and calculate V.

V=π r^2 h

SubstituteII

r= 4.2, h= 7.4

V=π ( 4.2)^2 ( 7.4)
