Why is the volume of a sphere 4/3πr^3?
- ColinWright 5y agoI wrote two blog posts about this some time ago: https://www.solipsys.co.uk/new/ConsideringASphere.html?uh14hn https://www.solipsys.co.uk/new/ConsideringASphere.html?uh14h... https://www.solipsys.co.uk/new/VolumeOfASphere.html?uh14hn https://www.solipsys.co.uk/new/VolumeOfASphere.html?uh14hn Pretty sure I posted them here on HN and they sank without trace, but readers might find them interesting.
- marcodiego 5y agoSimplest way I know to calculate volume of a sphere uses Cavalieri's principle and shows that the volume of an hemisphere is equals to the volume of the difference of a cylinder and a cone. Simple and beautiful.
