Question

Given the center (9,-7)^ and the radius of 6, determine the equation of the circle.

Answer 1

(x -9)^2 +(y +7)^2 = 36

Explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

For your given values, the equation is ...

(x -9)^2 +(y +7)^2 = 36
