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.

To find Circumference, we multiply the diameter by pie, since the formula is 3.14 x 2r. Your answer is 30.772
