Exercise 2 Page 721

Use the formula for the volume of a cylinder.

339 in^3

Practice makes perfect

We are given the following cylinder, and we want to find its volume.


The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=Ï€ 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=Ï€ r^2 h
V=Ï€( 3)^2 ( 12)
â–¼
Simplify right-hand side
V=Ï€(9)(12)
V=108Ï€
V=339.292006...
V≈ 339

The approximate volume of the given cylinder is 339 in^3.
