Dhululubo

Ka Wikipedia
U bood: gooshitaan, raadi

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

  • 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)

Mugga

Dhululubo socod waniin
Mugga waxaa lagu helaa:
(V) =   \pi r^2h \,
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
