Answer:
A = 28.26 ft^2

Explanation:

The formula for the area of a circle is: A = π
r^2

We need to plug in the values from the question into the formula.

  • r = 3 feet
  • use 3.14 for π


A = (3.14)(3)^2

A = (3.14)(9)

A = 28.26

Don't forget the units! Since we found the area of the circle, we need to square the units.


A = 28.26 ft^(2)
