Okay finding circumference from knowing the radius right? The radius is equal to half the diameter and circumference is equal to pi * diameter. So double the radius and multiply it by 3.14 then you will get the circumference!

Divide the circumference by pi which is 3.14 to find the diameter; then divide the diameter by two to find the radius GOOD LUCK
