Question

What is the volume of a cylinder with a height of 2 feet and a radius of 6 feet?

Use 3.14 for pi.

please help me use this for a study guide i have a test tomorrow!!

Answer 1

The volume of the cylinder is 226.08 feet^3

Explanation:

The volume of a 3-d shape with sides straight up is

BaseArea × height.

For a cylinder the base is a circle. Area of a circle is pi•r^2

So the Volume of your cylinder is:

V = pi•r^2 • h

Fill in the info given.

V = 3.14 • 6^2 • 2

= 226.08

The units for volume are cubed, that is, 3rd power.

So 226.08 cubed ft

or 226.08 ft^3

Hope this helps!

Answer 2

The volume of a cylinder is πr²h.

Given, that H = 2 ft and R = 6 Feet.

So V = πr²h = 3.14 x 6 x 6 x 2

= 3.14 * 72

= 226.08 ft³
