Exercise 6 Page 834

Use the formula for the volume of a cylinder.

1357.2 m^3

Practice makes perfect

The given solid is a cylinder.

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h By Cavalieri's Principle, the formula still holds true for oblique cylinders. 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= 6, h= 12

V=π ( 6)^2 ( 12)
