Geli dhexroorka ama dhererka dhexroorka si aad u xisaabiso mugga goobeedka.
Kani waa xisaabiye si gaar ah u xisaabiya mugga sephere ama kubbadda, taageerada metric iyo cutubyada Imperial (inji, cagaha, yard, mm, cm ama mitir), iyo natiijada mugga waxay u beddeli kartaa unug kala duwan, oo leh qaacido xisaabin iyo muuqaal firfircoon. Shere, waxay naga caawinaysaa inaan helno jawaabo oo aan si sahlan u fahanno natiijooyinka.
Goobtu waa shay joomatari wareegsan oo dhammaystiran oo saddex cabbir leh, iyadoo bar kasta oo korkeeda ku taal ay u dhiganto badhtankeeda. Walxaha sida caadiga ah loo isticmaalo sida kubbadaha ama globes waa goobo. Haddii aad rabto inaad xisaabiso mugga goobeedka, waa inaad heshaa raadiyeheeda oo aad gelisaa qaab fudud,
V = 4⁄3πr³.
Qaaciddada mugga goobeedka waa 4/3 jeer pi jeer cubed-beelka. Isku-duubista nambarku waxay la macno tahay in laftigeeda lagu dhufto saddex jeer, xaaladdan, radius-ku wuxuu ku dhuftaa raadiyaha.
Soo hel mugga goobeed leh radius 4 inji.
Haddii aan rabno in aan halbeegyada mugga u beddelno unugyo kala duwan, waxaan marka hore halbeegyada radius u beddeli karnaa isla mugga.
tusaale ahaan,
goob leh radius 9 inji ah.
Waa maxay mugga ft³?
Haddii aan haysano tirada dhexroorka oo kaliya, dhexroorka kala badhku waa radius, kaliya u qaybi dhexroorka 2, waxaanu yeelan doonaa radius.
