Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet), area = pi*502 = 1963.5 sq feet
If radius=21 ft, then diameter = 2*radius = 42 ft
Assuming the 100 ft refers to the diameter, radius = 50 feet. Area = pi*r2 = pi*2500 = 7853.98 sq ft (approx).
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16-ft, radius = 8-ft, and area = (pi) (8)2 = 201.062 square feet (rounded)
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
5.6433 ft radius or 11.2866 diameter
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet), area = pi*502 = 1963.5 sq feet
If radius=21 ft, then diameter = 2*radius = 42 ft
circle with radius with 22yd
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.
Assuming the 100 ft refers to the diameter, radius = 50 feet. Area = pi*r2 = pi*2500 = 7853.98 sq ft (approx).
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.
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
A circle with a radius of 100 units has a circumference of 628.32 units.
what is the approximate area of a circle with a radius of 26ft
Radius of circle: 10/2 = 5 feet
