Okuqukethwe
Kulolu shicilelo, sizocubungula indlela yokuthola i-radius yendilinga ezungezwe mayelana ne-cone, kanye nendawo yayo engaphezulu kanye nomthamo webhola eliboshwe yilo mkhakha.
Ukuthola indawo engaba yindilinga/ibhola
Noma yimuphi angachazwa. Ngamanye amazwi, ikhoni ingabhalwa kunoma iyiphi i-sphere.
Ukuthola indawo engaba yindilinga (ibhola) ezungezwe mayelana nekhoni, sidweba ingxenye ye-axial yekhoni. Ngenxa yalokho, sithola unxantathu we-isosceles (kithi - ABC), okuzungeza kuyo indilinga enobubanzi r.
I-cone base radius (R) ilingana nengxenye yesisekelo sikanxantathu (BC), kanye namajeneretha (l) - izinhlangothi zayo (AB и BC).
Irediyasi yombuthano (r)kuzungeza unxantathu ABC, phakathi kwezinye izinto, i-radius yebhola elizungezwe mayelana nekhoni. Itholakala ngokwamafomula alandelayo:
1. Nge-generatrix kanye nerediyasi yesisekelo sekhoni:
2. Ngobude kanye ne-radius yesisekelo sekhoni
Ukuphakama (h) Ikhoni ingxenye BE ezithombeni ezingenhla.
Amafomula wendawo kanye nevolumu ye-sphere/ibhola
Ukwazi irediyasi (r) ungathola indawo engaphezulu (S) izinhlayiya nevolumu (V) i-sphere eboshwe yilo mkhakha:
Qaphela: π ukuzungeza kulingana no-3,14.
