Question 781220
Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.) Center C(-6,7), passing through P(3,2)
***
Standard form of equation for a circle:
{{{(x-h)^2+(y-k)^2=r^2}}}, (h,k)=(x,y) coordinates of center, r=radius
..
(3+6)^2+(2-7)^2=r^2
9^2+(-5)^2=r^2
81+25=r^2
r^2=106
Equation of given circle: 
{{{(x+6)^2+(y-7)^2=106}}}
