Question

How do you even solve these?

Enter the equation of the circle described below.

Center (3, -2), radius = 5

Answer 1

The equation takes the x coordinate of the vertex and puts it into an equation in vertex form with the y coordinate and the radius. The radius is entered as its squared value. The general form of a circle is (x-h)^2 + (y-k)^2 = r^2. So yours would look like this: (x-3)^2 + (y+2)^2 = 25
