WebSo 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 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 ... WebArea of a circle: A = π r 2 = π d 2 /4 Circumference of a circle: C = 2 π r = π d. Circle Calculations: Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable. …
