Question

If a circumference is 12 pi ft what is the area

Answer 1

Answer: 36pi square feet

Work Shown:

Use the circumference to determine the radius.

C = 2pi*r

12pi = 2pi*r

12 = 2r

r = 12/2

r = 6

Then find the area.

A = pi*r^2

A = pi*6^2

A = 36pi

The units for the area will be "square feet" which can be abbreviated to "sq ft", ft^2 or
`\text{ft}^2`
