Helitaanka aagga lakabka wareegsan

Daabacaaddan, waxaan tixgelin doonaa hababka loo isticmaali karo si loo xisaabiyo bedka dusha lakabka wareegsan (jeex kubbadda): spherical, saldhigyada iyo wadarta.

Qeexida lakabka wareegsan

Lakabka wareegsan (ama jeex kubbadeed) - Tani waa qaybta ka hadhay inta u dhaxaysa laba diyaaradood oo isbar-bar socda. Sawirka hoose waa midab huruud ah.

• R waa raadiyaha kubbadda;
• r₁ waa radius saldhigga ugu horreeya ee la gooyey;
• r₂ waa radius saldhigga labaad ee la gooyey;
• h waa dhererka lakabka wareegsan; toosan laga bilaabo bartamaha saldhigga koowaad ilaa bartamaha kan labaad.

Formula lagu helo aagga lakabka wareegsan

dusha wareegsan

Si aad u hesho aagga dusha sare ee lakabka spherical, waxaad u baahan tahay inaad ogaato radius kubbadda, iyo sidoo kale dhererka goynta.

S_{degmada spheres} = 2 πRh

Saldhigyada

Baaxadda saldhigyada jeexjeexa kubbaddu waxay la mid tahay shayga afargeeska ah ee raadiyaha u dhigma lambarka π.

S₁ =r₁²

S₂ =r₂²

Oogada buuxda

Baaxadda guud ee lakabka wareegsan waxay la mid tahay wadarta meelaha dusha sare ee wareegsan iyo labada saldhig.

S_{degmada buuxda} = 2 Rh + πr₁² +πr₂² = π(2Rh + r₁² +r₂²)

Notes:

• haddii halkii radii (R, r₁ or r₂) dhexroor la siiyay (d), kan dambe waa in loo qaybiyaa 2 si loo helo qiyamka raadiyaha la rabo.
• qiimaha lambarka π marka la samaynayo xisaabinta, waxaa badanaa lagu soo koobaa laba jajab tobanle - 3,14.
