250 sq.ft. is the area
of the circle.
Apply the Area eq'n
A = pi r^2
Algebraically rearrange
r^2 = A/ pi
r = sqrt(A/pi)
Substituting
r = sqrt( 250/3.141592....)
r = sqrt(79.57747165...)
r = 8.920620581.... ft.
r = 8 ft 11.047... inches. ~ 9ft

If a circle has 87120 square feet what is the radius?
pi*r2 = 87120 sq ft so r2 = 87120/pi = 27731 sq ft and then r = 166.5 ft.
What is the area in feet of a 12 inch circle?
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter of the circle is 12 inches, the radius would be half of that, which is 6 inches. Converting inches to feet (1 foot = 12 inches), the radius would be 0.5 feet. Plugging this into the formula, the area of a 12-inch circle would be approximately 0.785 square feet.
What are the dimensions of a semicircle with an area of 200 sq ft?
area of full circle = 400 sq. ft. if area = pi * radius2 then radius = square root ( area / pi ) = 11.284 radius (approx). = 22.568 diameter (approx).
How do you calculate the sq ft of a 6.6 foot circle rug?
First you determine the radius of the circle. If 6.6 feet refers to the diameter, divide that by 2 to get the radius. Then you use the standard formula for the area of a circle.
What is the area of a circle with a diameter of 100 feet?
7850 sq ft. Formula is pi x R squared. Diameter of 100 means Radius (r) is 50. 50 squared (multiplied by itself) is 25000. Multiply THAT by the value of pi- or 3.14, and you get 7850 sq ft.
