Quandaries and Queries


I have a question. You know when you find the volume of sphere? I know the formula is V= 4/3 π r3 but why do they use 4/3? Can you explain this?  PLEASE answer soon! : )
Thank you soo much.


Hi Lauren,

This is a hard question to answer. The "modern" answer is to use calculus. By modern I mean since the seventeenth century. There is also a geometric construction due to Archimedes from the second century BC that shows where the 4/3 arises. You can see an outline of Archimedes' construction in Walter's answer to a previous question and also in Harley's answer to the same question asked earlier.
