Find the radius( r) for the circle. The radius is any line segment from the center of the circle to any point on its circumference. In this case, ( r) is the distance between ( (2,-2)) and ( (-5,-1)). ( r=5√2) ( ((x-h))^2+((y-k))^2=r^2) is the equation ...
Divide the circumference by 2 pi to find the radius if you know c. it's impossible to write the exact value of pi, but for most problems 3.14 is a good enough approximation. So, if your circumference is 618, you would get r = 618 / 2 pi r = 618 / 2 x 3.14 r = 618 / 6.18...
