How do you get circumfrence of a circle?

Answer 1

The circumference of a circle can be found by multiplying its diameter (the distance from one point on the circle to its opposite point) by the irrational number pi.

The value of pi is about 3.14, but it has an infinite number of nonrepeating digits. The circumference can also be expressed as 2(pi)r, where r is the radius. The radius is the distance from the center of the circle to any point on the circle. It is equal to half of the radius.

Answer 2

take the diameter and multiply by 3.14 or take the radius multiply it by it self and then multiply by 3.14
