Kutsvaga radius/nzvimbo/vhoriyamu yebhora (bhora) rakatenderedzwa necylinder

Muchinyorwa chino, tichaona kuti tingawana sei radius yebhora rakatenderedzwa kutenderedza silinda yekurudyi, pamwe nenzvimbo yaro uye huwandu hwebhora rakasungwa nebhora iri.

Kutsvaga radius yebhora/bhora

Nezve chero ipi zvayo inogona kutsanangurwa (kana mune mamwe mazwi, shandisa cylinder mubhora) - asi imwe chete.

• Pakati penzvimbo yakadaro ichava pakati pe cylinder, kwatiri isu ipfungwa O.
• O₁ и O₂ ndidzo nzvimbo dzezvigadziko zvehumburumbira.
• O₁O₂ - humburumbira kureba (H).
• OO₁ = OO₂ = ^h/₂.

Zvinogona kuonekwa kuti radius ye circumscribed sphere (URI), hafu yehurefu hwehumburumbira (OO₁)  uye upamhi hwechigadziko chayo (O₁E) gadzira gonyo rekurudyi OO₁E.

Tichishandisa izvi tinogona kuwana hypotenuse yegonyonhatu iyi, inovawo radius yebhora rakatenderedzwa pamusoro pehumburumbira yakapihwa:

Kuziva radius ye sphere, unogona kuverenga nzvimbo (S) pamusoro uye huwandu hwayo (V) bhora rakaganhurwa nebhora:

• S = 4 ⋅ π ⋅ R²
• S= ⁴/₃ ⋅ π ⋅ R³

Cherechedza: π yakatenderedzwa yakaenzana ne3,14.
