If you double the radius of a circle, you also double its circumference.It's now 200% of what it was originally ... an increase of 100% .See rigorous proof below.===========================================Let radius = rCircumference = 2πrDouble the radius:New radius = 2rNew circumference = 4πrIncrease in circumference = 4πr - 2πr = 2πr = (2πr/2πr) X 100%=100%
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. 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.

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)
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
If the circumference is 34.54, the radius is 5.497211734394065.
If the circumference is 24 the radius will be: 3.82
