Answer :

the equation for the circle is given as (x + 1)² + (y - 4)² = 221.

The endpoints of the diameter are:

(13, -1) and (-15, 9)

Distance between the points:

D = √(x₂ - x₁)² + (y₂ - y₁)²

D = √(-15 - 13)² + (9 +1)²

D =√784 + 100

D = √884

Diameter is:

d = 2√221

Radius is:

r = √221

Center will be:

x = (13 + (-15) / 2) = -1

y = (- 1 + 9 ) / 2 = 4

C = (-1, 4)

Equation for the circle:

(x + 1)² + (y - 4)² = 221

Therefore, we get that, the equation for the circle is given as (x + 1)² + (y - 4)² = 221.
