u can find it out by formula that is $$\frac{ 4 }{ 3 }\pi r ^{3}$$

mrnood · Answer

well = since pi is irrational you cannot calculate it 'exactly'

the formula is vol = pi r^3 * 4/3

anonymous · Answer

ok

anonymous · Answer

r is the radius of sphere

anonymous · Answer

$$vol=\frac{ 4 }{ 3 }\pi 12.3^{3}$$
can u solve it now

mrnood · Answer

I suppose you could state it 'exactly' by leaving pi in the answer, since it does represent a 'number'

ok thx guys

mrnood · Answer

The answer above has used pi = 3.14 (not exactly exact in my book)
