Helitaanka mugga iyo

Meesha sare ee dhululubo

>

>Waa maxay dhululubo?>Waxaa jira noocyo kala duwan oo dhululubo ah. Boggaan waxaan kaga hadli doonaa qaabka ugu fudud ee dhululubada u eg tuubo ama qasac maraq ah oo leh laba wareeg oo dhinac kasta ah oo isku le'eg oo isbarbar socda.

> >

Shuruudaha dhululubo>

Si loo xisaabiyo bedka iyo mugga dhululubada waxaan marka hore u baahannahay inaan fahamno dhowr eray:

>Radius - Radius-ku waa fogaan u dhexeeya bartamaha ilaa cidhifka wareegyada ee daraf kasta>Pi - Pi waa lambar gaar ah oo loo isticmaalo goobo. Waxaan isticmaali doonaa nooca la soo gaabiyey halka Pi = 3.14. Waxaan sidoo kale isticmaalnaa calaamadda π si aan u tixraacno tirada pi ee qaaciidooyinka.

Dheer - Dhererka ama dhererka dhululubada.

Aagga sare ee Silinder <4

Meecada dhululubo waa bedka labada goobaab ee daraf kasta oo lagu daray aagga bannaanka tuubada. Waxaa jira qaacido gaar ah oo loo isticmaalo in tan lagu garto.

Meecada dusha sare = 2πr2 + 2πrh

r = radius

h = height

π = 3.14

Tani waxay la mid tahay odhaahda (2 x 3.14 x radius x radius) + (2 x 3.14 x radius x dhererka)

>

Tusaale:

<3 Waa maxay bedka dhululubo oo leh radius 3 cm dhererkeeduna yahay 5 cm?

Meecada dusha sare = 2πr2 + 2πrh

= (2x3.14x3x3) + (2x3.14x3x5) <4

= 56.52 + 94.2

>

= 150.72 cm2

muggaDhululubo

Waxaa jira qaacido gaar ah oo lagu helo mugga dhululubada. Mugga ayaa ah inta boos ee ay qaadanayso gudaha dhululubada. Jawaabta su'aasha mugga waxay had iyo jeer ku jirtaa unugyo cubic

>

> Mugga = πr2h

Tani waxay la mid tahay 3.14 x radius x radius x dhererka

Tusaale:

Soo hel mugga dhululubo leh radius 3 cm dhererkiisuna yahay 5 cm?

Mugga = πr2h

= 3.14 x 3 x 3 x 5

= 141.3 cm 3

Sidoo kale eeg: Roomaankii hore: Sharciga Roomaanka >

>Waxyaabaha ay tahay in la xasuusto >

  • Meeca dushiisa ee dhululubo = 2πr2 + 2πrh
  • Mugga dhululubo = πr2h
  • Waxaad u baahan tahay inaad ogaato radiuska iyo joogga si aad u qiyaasto mugga iyo bedka dhululubada. Dhibaatooyinka aagga dusha sare waa inay ahaadaan had iyo jeer unugyo labajibaaran
