Question 779055: *Write the equations of the circle that satisfies each set of conditions*
1) The circle passes through (7,-1) and has its center at (-2,4).
Also, can you please show me how to solve this?
Thank you so much!

*Write the equations of the circle that satisfies each set of conditions*
1) The circle passes through (7,-1) and has its center at (-2,4).
------------------
The distance from the center to the point is the radius.
Find the distance.
r%5E2+=+diffy%5E2+%2B+diffx%5E2+=+5%5E2+%2B+9%5E2
r%5E2+=+106
------------
A circle's equation with the center at (h,k) & radius r is
%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2
==============================
%28x%2B2%29%5E2+%2B+%28y-4%29%5E2+=+106 is the circle.
