Bala umphezulu woMmandla weCone

NguMark Ryan

Ukubala umphezulu wekhowuni, kufuneka wongeze indawo yesiseko sekhowuni kwindawo yaso esecaleni. (I Indawo esecaleni ligama elihle lendawo yomphezulu edibanisa isiseko kwincopho; Ngamanye amagama, yonke into ngaphandle kwesiseko.)



Ikhonkco yejometri

Ikhowuni kunye nokuphakama kwayo kunye nokuphakama kwesilayidi.



Le fomyula ilandelayo ikunika umphezulu wekhowuni.

Nantsi imvelaphi ethe kratya kummandla osecaleni:

Indawo esecaleni yecone ngunxantathu omnye oqengqelwe kwimo yekone enjengekomityi yekhephu (luhlobo lonxantathu kuphela kuba xa icabalelekile, licandelo lesangqa elinecala elingaphantsi eligobileyo). Indawo yayo yile

Ukuphakama kwejometri



Ngoku ingxaki yekona:

Nanku umzobo wobungqina.

Ubungqina be-geometry-cone

Kwindawo engaphezulu, ekuphela kwento oyifunayo kukuphakama kwesilayidi, l . Ukuphakama kwesilayidi yi-hypotenuse kanxantathu engama-30-60-90, yiyo loo nto iphindwe kabini kwiradiyo, eyenza

ijiyometri-ezine-square-ezintathu

Ngoku fakela yonke into kwifomula yommandla wekhowuni:
