WebThe circumference is the distance around the circle. In other words, the circle's perimeter. The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle. Hope this helps! 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.
