I think C
we should add dead space from the tube, that is pi*R*R *lengh = 3.14*0.5*0.5*100=nearly 80
so total dead space = 150+80= 230 (i round it)

Well done. correct answer is C. How do we know that pi is 3.14? Or could you post where I can find the formula?
Thx

When robin082006 mentioned pi, I thought that there must be something complicated. Actually, everything is simple: it's the number that equals 3.142. below is the formula for measuring the volume of cylinder. I really hope we won't deal with other shapes.

My God, I have calculated 3x5x5x1000=75000mm3=75ml
but can't find this answer, then pick 150ml
forget to add them together
