Assuming 14 is the diameter of the circle, you would use the equation pi(r)^2 to find pi(7)^2 is your answer. Don't have a calculator, so I'm gonna say 49pi is your final answer

pi is about 3.14, doing it by hand...

  • 3 * 49 = 147
  • .1 * 49 = 4.9
  • .04 * 49 = 1.96

Adding 147, 4.9, and 1.96 gives 153.86 square feet.

Using a calculator, with more digits of pi gives 153.9380
