WebTwo circle with centres O and O' are drawn to intersect each other at points A and B. Centre O of one circle lies on the circumference of the other circle and CD is drawn tangent to … 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...
