The object the math question is based around for reference is a cylinder

I know

V=pi*r^2*h

dv/dh = pi*r^2

h = 0.00192882t - 1..32( this line was h = -0.00192882t + 1..32 but the question said to multiply the line by -1)

dh/dt= 0.00192882

r = 4

So therefore if I do the rate of change part right right I should get

0.00192882/16pi = dv/dh

then if I integrate I get

h = 0.000378722921381t + c

Is this correct, I have a feeling I did something wrong because I'm not getting the answer I expected.

I expected a line sloping negatively from the 2nd quadrant through the 1st and then to the 4th
