What is the equation of the circle with radius, r = 11, and the center at (0, - 7)

A. x ^ 2 + (y + 7) ^ 2 = 121

B. (x + 7) ^ 2 + y ^ 2 = 121

C. (x - 7) ^ 2 + y ^ 2 = 11

D. x ^ 2 + (y - 7) ^ 2 = 11

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h) ² + (y - k) ² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given (h, k) = (0, - 7) and r = 11, then

(x - 0) ² + (y - ( - 7)) ² = 11², that is

x² + (y + 7) ² = 121 → A
