Explanation:

Explanation:

The general equation for a circle is


{(x - h)}^(2) + {(y - k)}^(2) = {r}^(2)

where (h, k) is the coordinates of the center of the circle and r is the radius. Since the circle passes through (4, 4) and (-4, -4), its center is located at the origin, which means its equation becomes


{x}^(2) + {y}^(2) = {( \sqrt{ {4}^(2) + {4}^(2) } )}^(2) = 32
