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=lr^{2}(2pi^{2}/t - (sin t)(cos t))

if the height is greater than the radius,

V=lr^{2}(2pi^{2}/t + (sin t)(cos t))

... I think. I could very well be wrong. This was a purely geometrical solution.
