Question

A) Find the standard formula of the equation of a circle that has a center of (-4,-2) and contains the points (-1,2).

B) find the general formula.

Answer 1

A) The standard formula of the equation of a circle that has a center of (-4,-2) and contains the points (-1,2) is (x + 4)2 + (y + 2)2 = 25.

B) The general formula for the equation of a circle is (x - h)2 + (y - k)2 = r2, where (h,k) is the center of the circle and r is the radius.
