# Biology multiple choice maths question volume of neutrophil watch

1. I ended up with 1526.5micrometres cubed as the volume of the neutrophil but it is wrong. The answer is D 2000micrometres cubed. Where have I went wrong? Thanks
2. The diameter of the cell is roughly 15um. Radius is therefore 7.5um. Plug 7.5 into the equation and you get roughly 2000.

Thanks but this still didn't work : (7.5)^3 x 4/3 x pi = 1767.15
I have just attached what I did even though it is wrong:
4. The question is not asking for an exact answer. The answer you got is relatively close to 2000, so you should put 2000 as your answer just because it is the closest.
