Dhululubo

Ka Wikipedia

Dhululubo Waa joomateri ay masaaxad saleedyadiisu yihiin goobo, taa oo masaaxada isku xirta salalku tahay laydi golxo lehBedka xaddidan

$A=2\pi r^{2}\,$ + $2\pi rh\,$

Dhululubo

Habka loo cabiro

(r) waa dhexroorka salka

(h) waa jooga dhululubada

(A) Waa bedka salka $A=\pi r^{2}\,$

(P) Wareega Salka waxaana loo cabiri karaa sidaan $P=2\pi r\,$

BedKa dhinaca = Wareega Salka × Jooga = $P\times h$
Bedka Salka Sare = $\pi r^{2}\,$
Bedka Salka Hoose = $\pi r^{2}\,$
Bedka Guud = $(2\times \pi r^{2})+(P\times h)$

Dhululubo socod waniin

Mugga waxaa lagu helaa:

(V) =

\pi r^{2}h\,

Iyadoo la isku dhufto Bedka salka iyo jooga =

A\times h

Sidoo kale Habkaan

Adigoo sidaan u cabira =

\pi \times \int _{0}^{h}[d(x)]^{2}dx
