whats the answer for the line segment joining A(-1,5) and B(-5,-7) is a diameter?

Hello sharei-ga:

If you have a circle whose diameter has endpoints at A(-1,5) and
B(-5,-7), the following is true about this circle:

* center is:   C(-3,-1)

* length of the radius is:   1/2 * sqrt(160)

* equation of the circle is:   x^2 + y^2 + 6*x + 2*y - 30 = 0

sqrt( ) is the square root function, i.e., sqrt(160) is the square
root of 160 or approximately 12.65.

If you have more specific questions about this circle, please ask me
(giving as much detail as possible) using the clarification procedure
- before you rate this answer.

Thanks.
