Question

A circle is centered at (7, 8) and has a radius of 11. Which of the following is the equation for this circle? (6 points)

(x − 7)2 + (y − 8)2 = 121
(x − 7)2 + (y − 8)2 = 11
(x + 7)2 + (y + 8)2 = 121
(x + 7)2 + (y + 8)2 = 11

I got answer B

Answer 2

equation of a circle:

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

where (h,k) is your center and r is your radius. notice how the r is squared.
