circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
3 times
The circumference of a circle if its radius is 3 is about 18.85
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
The radius is 3.
