The diameter of a circle has endpoints P(–10, –2) and Q(4, 6).
a.Find the center of the circle.
c.Write an equation for the circle.

• GEOMETRY -

The centre must be the midpoint of PQ
which would be C( (-10+4)/2 , (-2+6)/2 )
= C(-3,2)

radius is √( (4+3)^2 + (2-6)^2) = √65

equation:
(x+3)^2 + (y-2)^2 = 65
