G O O B O

Waxaa jira macnayaal kale ee la xiriira goobada oo loo baahan yahay inaan fahamno.


Barta-xudduntaWaa barta ku dhacda bartamaha goobada.


GacanWaa xarriiq ka bilaabma barta- xuddunta kuna dhamaata bar ka mid ah wareega goobada.

Waxaana loo soo gaabiyaa r isla markaana waxa uu la eg yahay dhexroorka barkiis.


Bed=WareegGoobo×Gacanka2=πr2{\displaystyle \mathrm {Bed} ={\frac {\mathrm {WareegGoobo} \times \mathrm {Gacanka} }{2}}=\pi r^{2}}


KoordaWaa xarriiq u dhexeysa laba barood oo wareegga goobada ku taala.

Muhiim ama qasab ma aha in xarriiqdaasi ay marto barta-xuddunta.


Tani waxa ay ku tusaysaa xarriiqmaha ka dhexsamaysa Goobada


DhexroorWaa xarriiq u dhexeysa laba barood ee goobada martana barta-xuddunta.

Waxaana loo soo gaabiyaa d.



QaansoWaa xarriiq is wadata oo dul saaran qeyb ka mid ah goobada.



Gabal goobeedWaxay soo koobtaa inta u dhexeeysa xarriiqa qaansada ee goobada iyo koordaha. Waxaa kaloo la dhihi karaa labada cirif ay ku dhamaadaan xarriiqda qaansada.



Qurub goobeed Waa inta u dhexeysa xarriiqda qaansada iyo laba xarriiq ee gacanka kuwaasoo ku xirmaaya labada cirif ee xarriiqa goobada.
