Question

If the radius of a circle is 15 units and the center

of the circle is (−3, 2), what is the equation of
the circle?
A. (x − 2)2 + (y + 3)2 = 30
B. (x + 2)2 + (y − 3)2 = 225
C. (x + 3)2 + (y − 2)2 = 225
D. (x − 3)2 + (y + 2)2 = 15
HELP ME PLEASE

Answer 1

(x+3)^2 + (y-2) ^2 = 225

Explanation:

We can write the equation of a circle in the form

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

where (h,k) is the center and r is the radius

(x- -3)^2 + (y-2) ^2 = 15^2

(x+3)^2 + (y-2) ^2 = 225
