What are the center and the radius of the circle whose equation is (x − 3)2 + (y + 3)2 = 36?
A. center= (3,−3); radius = 6
B. center= (−3,3); radius = 6
C. center= (3,−3); radius = 36
D. center= (−3,3); radius = 36

its either A or B im pretty sure its B, someone help?

It would help you to know that the equation of a circle whose center is (h,k) and whose radius = r is:

mertsj · Answer

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