Get radius from circumference
WebThe circumference of a circle and the area of a circle have one thing in common: the radius. If I were you I'd do it in two steps: - first calculate the radius using the circumference formula, - then calculate the area using the radius you just calculated :-) Hope that helps! 2 comments ( 7 votes) Show more... Magnus Schmeikal 9 years ago 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 ...
