Question 193719
a circle has a diameter of 4'3 9/16" what is the area of the circle in square inches? what is the area in square feet? 
Area = pi x r^2 
diameter = 51.5625 in
radius = 25.78125 in ; r^2 = 664.67
so area of circle = (pi)r^2 = 2088.12 sq. in.
area of circle in square feet = (2088.12 sq. in.)/(12^2 sq. in) = 14.5 sq ft
