Circumference given the diameter formula
WebTherefore, the circumference circle equation is C = 2 πr. Example 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the … WebSo if we take the principal root of 36, we get r is equal to 6. From there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we ...
