Question

Im lost and cant find how to do this in my lesson.
A circle is inscribed in a square whose vertices have coordinates R(0, 4), S(6, 2), T(4, -4), and U(-2, -2). Find the equation of the circle.

(x - 2)2 + y2 = 68
(x + 2)2 + y2 = 20
(x - 2)2 + y2 = 20

Answer 1

first draw it out. Then use the general formula for the equation of a circle and the coordinates to find the equation
