Whakauruhia te radius, te roa diameter ranei hei tatau i te rōrahi o te āwheo.

Ngā tātai rōrahi

He tātaitai tenei e tatau ana i te rōrahi o te sephere, te poi ranei, tautoko ine me te wae imperial (inihi, waewae, iari, mm, cm, mita ranei), ka huri te hua rōrahi ki te waeine rereke, me te tātai tātai me te tirohanga hihiri. awheawhe, ka awhina i a maatau ki te tiki whakautu me te maarama ngawari ki nga hua.

Me pehea te whakamahi i tenei tatauranga?

  1. Kōwhirihia ki te whakamahi i te diameter, te pūtoro ranei hei tātai i te rōrahi.
  2. Whakauruhia te roa o te diameter, te radius ranei
  3. Whakaaetia te whakaurunga ira, hautau ranei, hei tauira. 3.4, 1.7, 5 1/4, 3/5 ranei
  4. Kōwhirihia te waeine o te diameter, te pūtoro ranei
  5. Kōwhirihia te wae o te rōrahi e hiahia ana koe ki te mohio
  6. Ka tātai aunoa i ngā hua ka tauhohenga pāhekoheko.
  7. Ka whakaawhiwhia te hua o te tatauranga.

Me pēhea te tātai i te rōrahi o te āwheo?

Ko te awheawhe he mea hangahanga tino porowhita e toru nga ahu, ko ia tohu o te mata he rite te tawhiti mai i te pokapū. He awheawhe te maha o nga mea e whakamahia nuitia ana penei i te poi, te ao. Mena kei te pirangi koe ki te tatau i te rōrahi o te āwheo, me kimi noa i tōna pūtoro me te hono ki tētahi tātai māmā,
V = 4⁄3πr³.

Tātai Rōrahi awhero

Ko te tātai mō te rōrahi o te āwheo he 4/3 ngā wā pi te whakareatanga i te pūtoro porowhita. Ko te tapatapahia te tau ko te whakareatia i a ia ano kia toru nga wa, i tenei ahuatanga, ka whakarea te putoro i te putoro ki te taitoro.

V = 4⁄3πr³
Rōrahi awhiowhio = 4⁄3 × π × pūtoro × pūtoro × pūtoro
πko te ōwehenga o te porowhita o te porowhita ki tona diameter

Tauira tatau

Kimihia te rōrahi o te āwheo me te pūtoro 4 inihi.

Rōrahi = 4⁄3π4³
4 ÷ 3 × 3.141592653589793 × 4 × 4 × 4 = 268.082573106329.
Whai muri i te whakaawhiwhi, he 268.08 inihi pūtoru te rōrahi.

Ki te hiahia tatou ki te huri i nga waeine o te rōrahi ki ngā waeine rerekē, ka taea te huri i ngā waeine o te pūtoro ki te ōrite o te rōrahi tuatahi,
hei tauira,
he awhiowhio e 9 inihi te putoro.
He aha te rōrahi i roto i te ft³?

pūtoro 9 in = 9 ÷ 12 ft = 0.75 ft Rōrahi = 4⁄3π0.75³
4 ÷ 3 × 3.141592653589793 × 0.75 × 0.75 × 0.75 = 1.7671458676442584
i muri i te whakaawhiwhi, ko te rōrahi he 1.77 pūtoru pūtoru.

Mena kei a tatou te maha o te diameter, ko te haurua o te diameter ko te putoro, wehea noa te diameter ki te 2, ka whai tatou i te putoro.
