What is the equation of the circle? To determine the equation of a circle, we need the center and the radius. Center is the midpoint of the diameter's endpoints. The radius is 1/2 the length of the diameter... Using the distance formula to find the length: 36+64 Radius: 5 Center (h, k): (4, O) (to check, plug in both endpoints
