m=-4
you are subtracting all the numbers by 4 therefore they are all changing by -4
You can do this by comparing your equation to the general form of equation of a circle
( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9
so (a,b) = (-9,-6) and r = 3
so the answer is B
C. Because it only gives the measure of angles on line p and not line q
to find the volume you would multiply length width and height
