Identify the center and radius of the circle: \left(x-7\right)^2+\left(y+3\right) ^2=64

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

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
