A circle with a radius of 45 units has a circumference of 282.74 units.

Circumference = 2*pi*radius Radius = Circumference/(2*pi)

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.

To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr

Radius is 45.

divide the circumference (c) by pi (3.14) and then you have diameter. you will have to measure the radius by hand.

The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places

divide it by 3.141592653 then divide it by 2

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.

Circumference = 2*pi*radius So Radius = Circumference/(2*pi)

Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
