a.) state the midpoint of the line segment with the given endpoints.
b.) If thepoint you found is (a) is the center of a circle, and the other two points are points on the circle, find the length of the radius of the circle. (That is, find the distance between the center point and a point on the circle) Find the exact answer and simplify as much as possible.
