Answer:

hope it's help you

Explanation:

$radius = (10)/(2) = 5 \\ now \: the \: equation \: of \: circle \: is \: given \: by \\ (x - h) {}^(2) + (y - k) {}^(2) = {r}^(2) \\ (x + 2) {}^(2) + (y - 2) {}^(2) = {5}^(2) \\ x {}^(2) + 4x + 4 + {y}^(2) - 4y + 4 = 25 \\ {x}^(2) + {y}^(2) + 4x - 4y = 17$
