Volume of Cylinders - Item 20987 Question 1 of 7

You have a can that is in the shape of a cylinder. It has a volume of about 1,728 cubic centimeters. The height of the can is 22 centimeters. What is the approximate length of the radius? Use 3.14 for pi.

Answer 1

approximately the radius is 5 cm

Explanation:

The formula for Volume of a Cylinder is shown below:

Volume of a Cylinder:

`V=\pi r^2 h`

Where

V is the volume

r is the radius

h is the height

We know

V = 1728

h = 22

We substitute and find r:

`V=\pi r^2 h\\1728= (3.14)r^2(22)\\1728=69.08r^2\\r^2=25.014\\r=√(25.014) \\r=5.001`

So we can that approximately the radius is 5 cm
