Find the area of the circle. Use 3.14 or 22/7 for pi.

Question

1. 9ft (diameter)

Answer 1

Area = A= pi(r)^2 = (22/7)(9/2)^2 = (22/7)(81/4) = (11/7)(81/2) = 891/14 =about 63.64 square feet

Area = 63.64 ft^2

or use 3.14 for pi and get 63.59 ft^2

round off to one decimal and it's 63.6 ft^2

63.617 if you use 3.14159 for pi
