Exercise 34 Page 638

Use the formula for the volume of a cylinder.

314.2 in.^3

Practice makes perfect

The given solid is a cylinder with a radius of 2 inches and a height of 25 inches. To calculate the volume of a cylinder with radius r and height h, we can use 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

r= 2, h= 25

V=π ( 2)^2 ( 25)

▼

Evaluate right-hand side

Calculate power

V=π( 4)( 25)

Multiply

V=100π

Use a calculator

V=314.159265...

Round to 1 decimal place(s)

V≈ 314.2

The approximate volume of the given cylinder is 314.24 cubic inches.
