Exercise 36 Page 604

Recall the formula for the volume of a cylinder.

Approximately 206.4 ft^3

Practice makes perfect

A cylinder has a radius of 3.7 feet and a height of 4.8 feet. Let's start by drawing it.

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h Here the r is the radius and h is the height. We have enough information to find the volume of the cylinder.

V=π r^2 h

SubstituteII

r= 3.7, h= 4.8

V=π ( 3.7)^2 ( 4.8)
