need someone to check please
i got 2.5cm=25mm
d=25mm so radius=12.5mm
for formula i was given to find volume was
v=1.33(3.14)r^3
v=1.33(3.14)1953.125
so v=8156.640625mm^3 (8156.64mm^3)
is this correct?

I got using your figures 8179.19.  The formula for V had 1.33 what is this a formula for, a cone???

anonymous · Answer

the radius of a drop of oil in water

radar · Answer

That must be for a hemisphere, I just was questioning the 1.33.   Is there a reason you doubt your answer?

anonymous · Answer

was questioning the big number and teacher gave me that formula

radar · Answer

It does seem large, but mm isn't that large of a unit.  I used those figures on my calculator and my calc' has a pi key, and a cube key, so I figure you may be O.K. using abbreviated value for pi.

anonymous · Answer

ok thanks was just double checking my answer

radar · Answer

The answer would be in cubic mm.

anonymous · Answer

what do you mean?

anonymous · Answer

like mm^4?

radar · Answer

$$8156.64 mm ^{3}=(cubic )$$

anonymous · Answer

ok thanks again
