Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.

It means that if you take a circle and find its area, you must now find a square with the same area. We cannot square the circle.

50.2656 square inches The formula to find the area of a circle is ∏r2. Where ∏ is the mathematical constant and r is the radius of the circle. So 3.14 x 42. = 50.27 square cm or yds, (whatever the diameter was in).

Area of a circle = pi*radius2

same as for a whole circle

Area in square units = pi*radius2

it is square root of the area divided by pi

To find the Square Footage of a 6 foot circle (flat), we must use the equation for Circle Area:Circle Area = pi Ã— r2Since we know that Diameter = 6 feet we Therefore know that Radius = Diameter/2 = 3 feet = rSo, Since, the constant pi = 3.14159 (approximate), we now have all the numbers to put into our Circle Area equation:Square Footage of a 6 foot flat Circle = 3.14159 x 32= 3.14159 x (3 x 3)= 3.14159 x 9= 28.27431Therefore:The Square Footage of a 6 foot Flat Circle = 28.27431 Square Feet (Feet2)
