Mekhoa ea ho bala radius ea bolo (sphere)
Lintlha tse ka tlase li sebetsa feela ho . Mokhoa oa ho fumana radius o itšetlehile ka mofuta oa setšoantšo, nahana ka likhetho tse tloaelehileng haholo.
Phiramide e tloaelehileng ea khutlotharo
Setšoantšong:
- a - moeli oa motheo oa piramite, ke hore, ke likarolo tse lekanang AB, AC и BC;
- DE – bophahamo ba piramite (h).
Haeba boleng ba lipalo tsena bo tsejoa, joale fumana radius (r) bolo / sphere e ngotsoeng e ka fanoa ka foromo:
Taba e khethehileng ea piramite e tloaelehileng ea khutlotharo ke eona e nepahetseng. Ho eena, mokhoa oa ho fumana radius o tjena:
Phiramide e tloaelehileng ea quadrangular
Setšoantšong:
- a - moeli oa motheo oa piramite, ke hore AB, BC, CD и AD;
- EF – bophahamo ba piramite (h).
Radius (r) bolo/sekala se ngotsoeng se baloa ka tsela e latelang:
Phiramide e tloaelehileng ea hexagonal
Setšoantšong:
- a - moeli oa motheo oa piramite, ke hore AB, BC, CD, DE, EF, EA;
- GL – bophahamo ba piramite (h).
Radius (r) bolo / sphere e ngotsoeng e baloa ka foromo:
