Calculating the Circumference of a Circle
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle.
How to find the circumference of a circle:
The circumference of a circle can be found by multiplying pi ¶ (which is equal to 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.

Circumference of a circle is Pi x diameter. Circumference of a semicircle is a million/2 x Pi x d+d. Your welcome! This answer comes from an quite reference sheet, so there is not any could desire to be puzzled.
