m=(m=( -7+(-2 )/2, 3+(-3)/2

m=( -7+(-2 )/2, 3+(-3)/2

Coplanar points are points on the same plane. X, Y, Z are coplanar points.therefore

1.  An archeologist found the remains of an ancient wheel, which she then placed on a grid. If an arc of the wheel passes through A(-7,0), B(-3,4) and C(7,0), located the center of the wheel, and the standard equation of the circle defining its boundary.
