Q:The equation of a circle with radius 8 centered at (-5,8) is?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

%28x-%28-5%29%29%5E2+%2B+%28y-8%29%5E2 = 8%5E2,   or, which is the same, 

%28x%2B5%29%5E2+%2B+%28y-8%29%5E2 = 64.


You must know it as English alphabet.

Use the general equation for circle centered at (h,k) with a radius of R,
%28x-h%29%5E2%2B%28y-k%29%5E2=R%5E2

%28x-%28-5%29%29%5E2%2B%28y-8%29%5E2=8%5E2
%28x%2B5%29%5E2%2B%28y-8%29%5E2=64
