Volume of a cone
[edit]V=(base area)*height*√2/4=0.8radius²*height*√2 Gmac4247 (talk) 15:42, 5 February 2024 (UTC)
- You really don't see the difference between a part of a sphere and a part of a cone? Please don't advance your personal point of view on this project, if you have good reference (in academic magazine) then show it. --Infovarius (talk) 10:00, 7 February 2024 (UTC)
- I see the difference between the volume of a quarter cone with height=radius and the eighth of a sphere with equal radius as V(quarter cone)=(3.2radius²/4)*radius*√2/4 : V(eighth sphere)=(√(3.2)radius/2)³. I regard my personal point of view as a valid way to compare the volumes. I don't have any magazines, in which this is published. Gmac4247 (talk) 18:18, 20 February 2024 (UTC)
