Question

Find the equation of the circle whose center and radius are given.

center ( 7, -3), radius = 7

Answer 1

\[\rm Center(h,k)~Radius(r):(x-h)^2+(y-k)^2=r^2\]

Answer 2

hint:
the general equation of a circumference whose center is:
\[\Large \left( {{x_0},{y_0}} \right)\]
and radius \[\Large r\], is:
\[\Large {\left( {x - {x_0}} \right)^2} + {\left( {y - {y_0}} \right)^2} = {r^2}\]
