You need to find the area of the circle.

A = pi * r^2

A = 3.14 * 2.5^2

A = ?

Multiply your answer by #3.

What do you get?

or would i take the 2.5^2 and multiply it getting 5 then multiply that by 3.14 which is 15.7 multiplied by 3 equals 47.10

**Ms. Sue**, Wednesday, September 16, 2009 at 7:29pmA = pi * r^2

A = 3.14 * 2.5^2

A = ?

2.5 squared = 6.25

A = 3.14 * 6.25

A = 19.625 square feet

$3 * 19.625 = $58.875

Since the company probably rounds up the square feet, your cost would probably be $60.00.
