Question

A circle has its center at (-2, -3) and a radius of 3 units. What is the equation of the circle?

(x + 2)2 + (y + 3)2= 9

(x + 2)2 + (y - 3)2= 9

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

(x + 2)2 + (y + 3)2 = 3

Answer 1

center radius form for the equation of a circle is:

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

center is (h, k) an radius is r. identify your h, k, and r and put it in to the center radius form and simplify it.

Answer 2

so would it be the second one?

Answer 3

try again.

Answer 4

well if the r^2 and r=3 then its the first one

Answer 5

that's the one! :)

Answer 6

thanks!
