Area of a circle is defined as
A = pi x radius2
So if the diameter is 1 ft, the radius is 1/2 ft. I'll use pi=3.14. So the problem in feet is:
pi x (1/2)2 = 3.14 x 1/4 = .785 sq ft
In inches, radius = 6 inches so:
pi x 62 = 3.14 x 36 = 113.04 sq in

The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
Area of a circle = (1/4) x (pi) x (square of the diameter)
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
What's a "60 foot circle" ? Does that mean the diameter is 60-ft ?Area of a circle = (pi) (radius)2 .Radius = 1/2 diameterIf the diameter is 60-ft, then area = (pi) (30)2 = (900 pi) = 2,827.43 square feet (rounded)
