Hi,
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
