How to solve circumference with diameter
WebThis tool will calculate the circumference of a circle from the diameter, and will convert different measurement units for diameter and circumference. Formula The formula used to calculate circle circumference is: C = π · ø Symbols C = Circle circumference π = Pi = 3.14159… ø = Circle diameter Diameter of Circle Enter the diameter of a circle. WebCircumference 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 leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference was 12pi. Up next: video
