Question

Write the equation of a circle who’s center is (6,-7) and who’s radius is 4

Answer 1

(x-6) ^2 + (y+7)^2 = 16

Explanation:

We know the equation of a circle is given by

(x-h) ^2 + (y-k)^2 = r^2 where ( h,k) is the center and r is the radius

(x-6) ^2 + (y- -7)^2 = 4^2

(x-6) ^2 + (y+7)^2 = 16
