Question

This circle is centered at the point (-2, 5), and the length of its radius is 2. What is the equation of the circle?



A. (x + 2)^2 + (y - 5)^2 = 2
B. (x^2 + 2) + (y^2 - 5) = 22
C. (x - 5)^2 + (y + 2)^2 = 4
D. (x + 2)^2 + (y - 5)^2 = 4

Answer 1

Im stuck between A and D

Answer 2

\[(x-h)^2+(y-k)^2=r^2\]where \((h,k)\) is the center and \(r\) is the radius

Answer 3

\[(x-\color{red}{(-2)})^2+(y-\color{red}{(5)})^2=\color{red}2^2\]solve it :)

Answer 4

I think it's a!?

Answer 5

wait no scratch that

Answer 6

close....its 2 SQUARED, remember :)

Answer 7
