Daabacaaddani waxa ay soo bandhigaysaa qaacidooyin loo isticmaali karo in lagu helo raadiyaha kubbadda (Sphere) ee ku xardhan Ahraamta caadiga ah: saddex xagal, afargeesle, laba geesood iyo tetrahedron.
Foomamka lagu xisaabinayo raadiyaha kubbadda (sphere)
Xogta hoose waxay khusaysaa oo kaliya . Habka lagu helo raadiyaha waxay ku xiran tahay nooca shaxanka, tixgeli fursadaha ugu caansan.
Ahraamta saddex-geesoodka ah ee joogtada ah
Sawirka:
- a - cidhifka saldhigga Ahraamta, ie waa qaybo siman AB, AC и BC;
- DE - dhererka Ahraamta (h).
Haddii qiimaha tirooyinkan la yaqaan, ka dibna raadi radius (r) Kubbad/shere ku qoran waxa lagu bixin karaa qaacidada:
Kiis gaar ah oo ah Ahraamta saddex-geesoodka ah ee caadiga ah ayaa ah midka saxda ah. Isaga, qaacidada lagu helo raadiyaha waa sida soo socota:
Ahraamta afargeesoodka ah ee joogtada ah
Sawirka:
- a - cidhifka saldhigga Ahraamta, ie AB, BC, CD и AD;
- EF - dhererka Ahraamta (h).
gacan (r) Kubbad/sfeer-qoran ayaa loo xisaabiyaa sida soo socota:
Ahraamta laba geesoodka ah ee joogtada ah
Sawirka:
- a - cidhifka saldhigga Ahraamta, ie AB, BC, CD, DE, EF, OF;
- GL - dhererka Ahraamta (h).
gacan (r) Kubbad/shere ku qoran waxaa lagu xisaabiyaa qaacidada:
