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

Answer 1

Answer:

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

Step-by-step explanation:

The equation of the circle is (x-h)^2 +  (y-k)^2 = r^2

h=-3, k=2 and r=15

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

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