Question

Which equation represents a circle with a center at (-3,5) and a radius of 6 units

Answer 1

(x+3)^2 +(y-5)^2 = 36

Explanation:

We can write the equation of a circle as

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

(x- -3)^2 +(y-5)^2 = 6^2

(x+3)^2 +(y-5)^2 = 36
