1. Volume of Cylinders

Continue to next subchapter

Exercise 1 Page 592

Recall the formula for the volume of a cylinder, V = π r^2 h.

About 56.5 cm^3

Practice makes perfect

Consider the given cylinder. Its radius is 1.5 centimeters and its height is 8 centimeters.

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h Now, we can substitute the given values into the formula and calculate V.

V = π r^2 h

r= 1.5, h= 8

V = π ( 1.5)^2( 8)

▼

Simplify right-hand side

Calculate power

V = π (2.25)(8)

Multiply

V = π (18)

Use a calculator

V = 56.548668...

Round to 1 decimal place(s)

V ≈ 56.5

The volume of the given cylinder is about 56.5 cubic centimeters.
