Question

The equation of a circle is ​ (x+14)²+(y+8)²=121 ​ .


What is the circle's radius?

Answer 1

121

Explanation:

in a circle equation, it is (x+h)^2+(y+k)^2=r, and -(h,k) is the equation of the center and the r is radius.

By -(h,k) I mean whichever symbol before h or k, the corresponding coordinate is the opposite.

Best of luck to you!
