Mukati
Muchinyorwa chino, isu tichatarisa fomula yaunogona kuverenga nayo huwandu hwechikamu chechikamu, pamwe nemuenzaniso wekugadzirisa dambudziko kuratidza mashandisiro ayo mukuita.
Kutsunga kwechikamu chebhora
Chikamu chebhora (kana chikamu chebhora) chikamu chine chikamu chakatenderera uye koni, iyo yepamusoro iyo iri pakati pebhora, uye hwaro ndihwo hwaro hwechikamu chinoenderana. Mumufananidzo uri pasi apa, chikamu chacho chine shaded mune orenji.
- R ndiyo radius yebhora;
- r ndiyo radius yechikamu uye cone base;
- h - chikamu chakareba; perpendicular kubva pakati pechigadziko chechikamu kusvika pane imwe nzvimbo padenderedzwa.
Formula yekutsvaga huwandu hwechikamu chesphere
Kuti uwane huwandu hwechikamu chedenderedzwa, zvinodikanwa kuti uzive radius yepasirendi uye kureba kwechikamu chinoenderana.
Notes:
- kana panzvimbo yeradius yebhora (R) kupihwa dhayamita yayo (d), iyo yekupedzisira inofanira kukamurwa nembiri kuti iwane radius inodiwa.
- π yakatenderedzwa yakaenzana ne3,14.
Muenzaniso wedambudziko
Sphere ine radius ye 12 cm inopihwa. Tsvaga huwandu hwechikamu chakatenderera kana kureba kwechikamu icho chikamu ichi chine 3 cm.
mhinduro
Isu tinoshandisa fomula yakakurukurwa pamusoro, tichitsiva mairi maitiro anozivikanwa pasi pemamiriro edambudziko:
