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

What is the area in feet of a 12 inch circle?
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
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 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.
What is the sq ft of a circle with 8 ft radius?
the questions is asking you to find the area, so the area of a circle is 3.14r^2. Plug 8ft for radius and you get your answer to be approximately 201.06 sq ft
What is sq ft of a 36ft circle?
Area of a circle = pi*radius squared
How many sq ft in a 2' circle?
Area of a circle = pi*radius squared
What is the sq ft of a 24 inch circle?
Area of a circle = pi*radius squared
How big is a circle to be 100 sq ft?
5.6433 ft radius or 11.2866 diameter
How do you measure sq ft of a circle?
If you meant: How does one measure the area of a circle in Sqft, The formula is: Pi x Radius in Ft squared. i.e. Area of circle in SqFt. =(22/7) x Radius in Ft x Radius in Ft.
How sq ft in a 4 ft circle?
If the diameter of the circle is 4 feet across the area is about 12.6 sq ft. You can check this by using the formula Area=Pi times the radius squared.
What is the sq footage of a circle with the diameter of 36ft?
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
What is the radius of a circle with a sector area of 7π sq ft?
Anything greater than 3.5 ft
Find the area of a circle 15 ft?
Area_circle = π × radius²It depends to what the 15 ft refers, if:15 ft is the radius of the circlearea = π × (15 ft)² = 225π sq ft ≈ 707 sq ft 15 ft is the diameter of the circlediameter = radius × 2 → radius = ½ diameter→ area = π × (15 ft / 2)² = 225π/4 sq ft ≈ 177 sq ft15 ft is the circumference of the circlecircumference = 2 × π × radius → radius = circumference ÷ (2π)→ area = π × (15 ft / 2π)² = 225/(4π) sq ft ≈ 17.9 sq ft
What is the area in feet of a 12 inch circle?
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
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.
