Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to find the radius and center of the circle given by the equation (x-7)²+(y+3)²=64
Changing equation to (x-h)²+(y-k)² = r² form
(x-7)²+(y+3)²=64
(x-7)²+(y-(-3))² = 8²
So, h = 7 , k = -3 and r = 8
Center is (7,-3) and radius is 8
