1. Problem Description

The problem asks to find the equation of a circle with center (2,5)(-2, 5) and radius 88.

2. Solution Steps

The general equation of a circle with center (h,k)(h, k) and radius rr is given by:
(xh)2+(yk)2=r2(x - h)^2 + (y - k)^2 = r^2
In this problem, the center is (2,5)(-2, 5), so h=2h = -2 and k=5k = 5. The radius is r=8r = 8.
Substituting these values into the general equation, we get:
(x(2))2+(y5)2=82(x - (-2))^2 + (y - 5)^2 = 8^2
(x+2)2+(y5)2=64(x + 2)^2 + (y - 5)^2 = 64

3. Final Answer

(x+2)2+(y5)2=64(x + 2)^2 + (y - 5)^2 = 64
