Question

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

(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

Answer 1

Remember that the standard form is \[(x-h)^2 + (y-h)^2 = r^2\]

Answer 2

So which one do you think
