Question

Answer Check: (x + 1)^2 + (y - 2)^2 = 3

A circle has its center at (-1, 2) and a radius of 3 units. What is the equation of the circle?

(x - 1)^2 + (y + 2)^2 = 3

(x + 1)^2 + (y - 2)^2 = 3

(x + 1)^2 + (y + 2)^2 = 9

(x + 1)^2 + (y - 2)^2 = 9

Answer 1

bad 3

you want r^2, not r

Answer 2

so it would be 3 instead of 9

Answer 3

9, instead of 3 ... yes

Answer 4

(x + 1)^2 + (y - 2)^2 = 9

Answer 5

perfect
