Mubhuku rino, tichaona kuti tingawana sei radius yebhora rakatenderedzwa pamusoro pekoni, pamwe nenzvimbo yaro uye huwandu hwebhora rakasungwa nebhora iri.
Kutsvaga radius yebhora/bhora
Chero munhu anogona kutsanangurwa. Mune mamwe mazwi, koni inogona kunyorwa mune chero nzvimbo.
Kuti tiwane radius yebhora (bhora) rakatenderedzwa pamusoro pekoni, tinodhirowa chikamu cheaxial chekoni. Nekuda kweizvozvo, tinowana isosceles triangle (munyaya yedu - ABC), denderedzwa rine radius r.
Cone base radius (R) yakaenzana nehafu yehwaro hwegonyo (BC), uye jenareta (l) - mativi ayo (AB и BC).
Radhiyasi yedenderedzwa (r)yakatenderedzwa kumativi matatu ABC, pakati pezvimwe zvinhu, iradius yebhora rakatenderedzwa pamusoro pekoni. Inowanikwa maererano nemaitiro anotevera:
1. Kuburikidza nejenararisi uye radius yehwaro hwekoni:
2. Kuburikidza nekukwirira uye radius yehwaro hwekoni
urefu (h) koni chikamu BE mumifananidzo iri pamusoro.
Maformula enzvimbo uye vhoriyamu yebhora/bhora
Kuziva radius (r) unogona kuwana nzvimbo yepamusoro (S) mativi uye volume (V) bhora rakaganhurwa nebhora iri:
Cherechedza: π yakatenderedzwa yakaenzana ne3,14.
