Exercise 2 Page 455

Use the formula for the volume of a cylinder.

62.8 cm^3

Practice makes perfect

The given solid is a cylinder.

We can calculate the volume of a cylinder with the radius r and height h using the following formula. V=π r^2 h We find V by substituting the radius and the height into the formula.

V=π r^2 h

SubstituteII

r= 2, h= 5

V=π ( 2)^2 ( 5)
