Area of a circle in square feet = pi*radius2

circumference = π x diameter => diameter = circumference ÷ π ~= 20ft ÷ 3.14 ~= 6.37 ft

The area of a circle with a diameter of 9.4 m is: 69.4 m2

Double the value of the radius which in this case is 2*20 = 40 feet

Assuming a diameter of 5 inches.The area of this circle is: 19.63
