Ukuthola umthamo wesendlalelo esiyindilinga

Kulolu shicilelo, sizocubungula amafomula angasetshenziswa ukubala ivolumu yesendlalelo esiyindilinga (ucezu lwebhola), kanye nesibonelo sokuxazulula inkinga ukuze kuboniswe ukusebenza kwazo okungokoqobo.

Incazelo yesendlalelo esiyindilinga

Isendlalelo esiyindilinga (noma ucezu lwebhola) – lena ingxenye esele phakathi kwezindiza ezimbili ezifanayo eziphambanayo. Isithombe esingezansi sinombala ophuzi.

• R iyiradiyasi yebhola;
• r₁ iyiradiyasi yesisekelo sokuqala sokusika;
• r₂ iyiradiyasi yesisekelo sokusika sesibili;
• h ukuphakama kongqimba oluyindilinga; perpendicular ukusuka enkabeni yesisekelo sokuqala kuya enkabeni yesibili.

Ifomula yokuthola ivolumu yesendlalelo esiyindilinga

Ukuze uthole umthamo we-spherical layer (ucezu lwebhola), udinga ukwazi ukuphakama kwayo, kanye ne-radii yezisekelo zayo ezimbili.

Ifomula efanayo ingethulwa ngendlela ehluke kancane:

amanothi:

• uma esikhundleni se-base radii (r₁ и r₂) amadiameter abo ayaziwa (d₁ и d₂), laba bakamuva kufanele bahlukaniswe ngo-2 ukuze bathole i-radii ehambisanayo.
• inombolo π ngokuvamile kufinyezwa ku-3,14.

Isibonelo senkinga

Thola ivolumu yongqimba oluyindilinga uma i-radio yezisekelo zayo ingu-3,4 cm no-5,2 cm, futhi ukuphakama 2 bheka.

Isixazululo

Okufanele sikwenze kuleli cala ukufaka amanani aziwayo kwelinye lamafomula angenhla (sizokhetha elesibili njengesibonelo):
