That quantity is usually called "area".
The area of any circle is (pi) (radius)2 .
Area = (pi) (11 inches)2 = 380.133 square inches (rounded)
To convert square inchage to square footage, divide by 144.
380.133 square inches = 2.64 square feet (rounded)
The radius of a circle with an area of 35 square inches is 3.34 inches.
A circle with a radius of 26 inches has an area of: 2,124 square inches.
The area of a circle if the radius is 2.5 inches is: 19.63 square inches.
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.
Radius is 30 inches.
The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
The radius of a circle with an area of 706.50 square inches is: 15 inches.
The radius of a circle with an area of 35 square inches is 3.34 inches.
A circle with a radius of 26 inches has an area of: 2,124 square inches.
Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
A circle with a radius of 11 inches has an area of 380.13 square inches.
The area of a circle if the radius is 2.5 inches is: 19.63 square inches.
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
A circle with a radius of 18 inches has an area of 1,017.88 square inches.
A circle with a radius of 3 inches has an area of 28.27 square inches.
Radius = 3.57 inches.
A circle with a radius of 5.1 inches has an area of 81.71 square inches.
