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 WebSince a radius is a a straight line from the center to the circumference of a circle, you could use the distance formula: √ (x2−x1)^2+ (y2−y1)^2; to find the distance from the center (0,0) to the point (-6,√37); which would give you the radius. 1 comment ( 5 votes) Upvote Downvote Flag more Show more...
