(x−h)2+(y−k)2=R2(x-h)^2+(y-k)^2=R^2 is a circle that is centred at (h,k)(h,k) that has radius R>0R>0.
Thus with this problem we have
x2+y2+16y+k=0(x−0)2+(y+8)2−64+k=0x2+(y+8)2=64−kx^2+y^2+16y+k=0\\(x-0)^2+(y+8)^2-64+k=0\\x^2+(y+8)^2=64-k
Now we are told that the radius is 1010 , so what?

Incorrect as noted in post #12.
Requirement (a) was already worked out for you by pka at post #5.
For requirement (b), you are asked to solve for k.
The problem states that the radius is 10.
You should first determine what the value of k is by equating 64 - k with [MATH]10^2[/MATH], or solve for k in [MATH]64 - k = 10^2[/MATH]After you do that, more hints will come your way.
