you have to use the formula : C= 2* radius* Pie symbol. * IS MULTIPLYING. Pie always equals to 3.14, so suppose the radius is 5. You would multiply 5*2*3.14.
Your answer would be 31.4.The reason you have to multiply the radius by 2 is because you have to make the radius turn into the diameter which is double the radius to make the equation simpler. Always remember to use pie as 3.14.

How do you convert basic circumference into radius?
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
What is the formula for finding the circumference with radius?
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.
How do you find a circumference of a circle if the radius is 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.

What is the circumference when the radius is r?
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
What is the circumference of a circle with a radius of Cm?
The circumference is twice the radius. In other words, if you know the radius, multiply it by 2 to get the circumference.
