Question

The diameter of a circle with endpoints A(-1,5) and B(4,-3) Use the midpoint formula to find the coordinates of the center of circle P(xy)

Answer 1

Since all 4 radii are shown to have the same length value of √10, we are confident that our calculations for center C and diameter endpoint E are correct.

Finally, we can also calculate the length of the diameter since it is simply twice the length of the radius:

radius = √10

diameter = 2√10
