WitrynaThe 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. WitrynaEvery school kid has been told that a circle of radius r has circumference = 2 π r. Here is a parameterization of a circle of radius r xx (θ) = ∇ cos (θ) yy (θ) = ∇ sin (θ) To get the whole circle, you run t from 0 to 2 π. Use this information to confirm that the circumference of a circle of radius r measures out to 2 π r units long.
