The equation of a circle:
(h,k) - the coordinates of the centre
r - the radius
The midpoint of the diameter is the centre of a circle.
The coordinates of the midpoint:
(x₁,y₁), (x₂,y₂) - the coordinates of endpoints
The centre of the circle is (2,5).
The radius is the distance between an endpoint of the diameter and the centre.
The formula for distance:
The radius is 5.
