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 = 3

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

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

Answer 1

@hartnn

Answer 2

(x - h)² + (y - k)² = r²

IS the standard form, where (h,k) is the center, and r is the radius.

Answer 3

so its D

Answer 4

Close... look at the equation again though, it says r² (NOT just r )

Answer 5

Oh okay... C

Answer 6

Yeah!!!

Answer 7

Thank you!!!
