The area of a 17-foot circle is: 227 square feet.
Area of a circle is found by: A = (Pie)(r2) Plug in 17 for 'r'. A = (Pie)(172) A = 907.920277 ft.
Surface area of a sphere = 4*pi*radius2 The diameter is 17 feet so the radius is half of this i.e. 8.5 feet. 4*pi*8.52 = 907.9202769 square feet.
Circumference in terms of PI = 17 PI Circumference with 3.14 = 53.58 Area in terms of PI is 72.25 Area with 3.14 is 226.86500
The formula for the area of a circle is A = ∏r ∏ = 3.142, r =1/2d = 8.5in A = 3.142 x (8.5)2in2 A = 227.0095in2
