# Hard problem involving derivates watch

1. An oiltank has the shape of a circular cylinder. The diamter is 1.24m and the length 2.44m. The tank is filled with a velocity of 0.0045m3 per second. How fast does the oil level rise in the moment the oildepth D is 0.32 m?

I presume the cylinder is horizontal.

So what have you done? Any thoughts?
