have you found the distance between the two points given. This length will be the diameter's. And we know the radius is half that much.

We also know that we need to find the midpoint of the line segment given to find the center.

$d=\sqrt{(-3-5)^2+(4-(-2))^2} \\ r=\frac{d}{2} \\ \text{ center is the midpoint of the line segment with endpoints } \\ (-3,4) \text{ and } (5,-2) \\ \text{ that is you need to compute the average of the x's } \\ \text{ and the average of the y's } \\ \text{ this is the center } =(\frac{-3+5}{2}, \frac{4+(-2)}{2})$

d=(−3−5)2+(4−(−2))2−−−−−−−−−−−−−−−−−−−√r=d2 center is the midpoint of the line segment with endpoints (−3,4) and (5,−2) that is you need to compute the average of the x's and the average of the y's this is the center =(−3+52,4+(−2)2)
