maybe im being stupid but I'm really confused;
question:
The volume of cell A is 5.4 × 104μm3.
Assume that cell B is spherical.
Calculate the volume of cell B.
Use the formula: volume of sphere = 4
3
πr3
how would i go about answering it, ive measured cell ,bearing in mind I think it's printed on wrong scale but even if i have wrong measurement idk where to go.........
the ms :
If cell B is measured and formula applied…
1.7 (± 0.4)
If working back from information given about cell A…
2.2 (± 0.4)
(number less than 10) x104 (μm3)
wot????????
thanks

how i went about, measured radius at 0.7cm, then i did actual size = 0.7cm / 1000(the mag.) so thats my size then i used equation and it just went horribly wrong......... maybe i converted units wrong idk
