Let the radius of the cylinder be r and the length be l. If the height of liquid on the dipstick is less than r,
if t=arccos((r-h)/r)
V=lr2(2pi2/t - (sin t)(cos t))
if the height is greater than the radius,
V=lr2(2pi2/t + (sin t)(cos t))
... I think. I could very well be wrong. This was a purely geometrical solution.
