Question

12 sphers of same size are made from melting a cylinder of 16 CM diameter and 2 centimetre height find the diameter of each sphere​

Answer 1

Answer:

The volume of sphere=4/3πr^3

The volume of cylinder=πr^2h

12×(4/3πr^3)=πr'^2h

16πr^3. =πr'^2h

16r^3=r'^2h

16r^3=8×8×2

r^3=8

√r^3=√8

r=2cm
