Depending on what "a circle of 480 feet" means, the radius will have different values.
If the radius is 480 feet, then that is your answer.
If the diameter is 480 feet, then its radius is 480/2 = 240 feet.
If the circumference is 480 feet, then its radius is 480/2(pi) = 240/(pi) = 76.39 feet.
A circle with a radius of 14 feet has an area of 615.75 square feet.
The radius of a circle, if its circumference is 420 feet, is 66.8 feet.
The area of a circle with a radius of 3 feet is: 28.27 square feet.
A circle with a radius of 6.8 feet has an area of 145.27 square feet.
A circle with a radius of 14 feet has a circumference of 87.96 feet.
Radius of circle: 480/2 = 240 inches
The formula for the circumference (C) of a circle is C = 2π r, where r is the radius. If 480 = 2π r, then r = 480/2π = 240/π = 76.394 inches (3dp)
A circle with a radius of 14 feet has an area of 615.75 square feet.
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
The radius of a circle, if its circumference is 420 feet, is 66.8 feet.
The radius of a circle with a circumference of 13 feet is: 2.069 feet.
The circumference of a circle if the radius is 2 feet is: about 12.57 feet.
A circle with a radius of 6 feet has a circumference of 37.7 feet.
A circle with a radius of 100 feet has a circumference of 628.32 feet.
If the radius of a circle is 8 feet the circumference is about 50.27 feet.
The circumference of a circle that has a radius of 40,200 feet is: 252,600 feet.
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
