Question

What's the equation for a circle of (2,-5) and a radius of 2

Answer 1

(x - 2)^2 + (y + 5)^2 = 2^2

Explanation:

Adapt the standard equation of a circle with center at (h, k) and radius r:

(x - 2)^2 + (y + 5)^2 = 2^2, where h = 2 and k = -5 and r = 2

Answer 2

(x+5)2+(y+5)2=22, or (x+5)2+(y+5)2=4.
