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), (-3 4) and (7, 0), locate the center of the wheel, and the standard equation of the circle defining its boundary.
The center is at (1,-2), and the equation is (x - 1)^2 + (y + 2)^2 = 50.
