Proof circumference of circle

WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that. (1)\quad\purpleC {\theta_1}=2\blueD {\psi_1} (1) θ1 = 2ψ1. and. 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...
