Question

Radius and a center located at (0, - 6) Which equation represents this circle?

A. x ^ 2 + (y + 6) ^ 2 = 11
B. x ^ 2 + (y - 6) ^ 2 = sqrt(11)
C.x ^ 2 + (y + 6) ^ 2 = sqrt(11)
D. x ^ 2 + (y - 6) ^ 2 = 11

Answer 1

A.

Explanation:

The center is at (0, -6) so the equation is:

(x - 0)^2 + ( y + 6)^2 = r^2

x^2 + (y + 6)^2 = r^2

r^2 = 11

Answer is x^2 + (y + 6)^2 = 11.
