A circle with a radius of 4 miles has a circumference of 25.13 miles.
Circumference = 34*pi miles
The equatorial radius 3,396.2 kilometers (2,110miles).The equatorial circumference of Mars is 21,339 kilometers (13,259 miles).Compared to Earth, the ratio is .533, i.e. the radius and circumference of Mars is about half the radius and circumference of Earth.
That depends on whether 10 miles is the diameter or circumference.
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
The radius is 1/2 of the circumference.
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
If the circumference is 20 the radius is 3.18
