WebIt is equal to twice the length of the radius. Circumference: the distance around the circle, or the length of a circuit along the circle. Arc: part of the circumference of a circle Major arc: an arc that is greater than half the circumference Minor arc: an arc that is less than half the circumference WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. 1 comment
