Pehea e loaʻa i ka ke kahahńnai o ka p ÷ ai: e kōkua i nā haumāna

Pehea e loaʻa i ka ke kahahńnai o ka p ÷ ai? Kēia ninau mea mau nui no nā haumāna këia planimetry. Aia ma lalo ke nana aku ma kekahi ano he kumu hoʻohālike o peheaʻoe ke Makuakane me ka hana.

Ke kaumaha ma muli o ka ke kahahńnai o ka p ÷ ai hana keia, e hiki i ke ala loaʻa.

Haʻilula 1: R = L / 2π, kahi A - o ke anapuni, a π - a eia i like i ka 3.141 ...

Haʻilula 2: R = √ (S / π), kahi S - o ka huina o ka wahi o ka p ÷ ai.

Haʻilula 3: R = D / 2 kahi D - o ke anawaena o ka pōʻai, a laila i ka lōʻihi o ka pauku i, maalo ae la oia ma ka waena konu o ka huahelu hoʻohuiʻia ka mau maximally kaulike 'Aʻohe wai iaʻu ka papa.

Pehea e loaʻa i ka ke kahahńnai o ka circumcircle

Mua e ka hoakaka i ka makahiki iho. kapa aku la i hoakakaia anapuni ia e pili ana i ka iieeaii vertices. It E e kaulana i ka hoa kanaka hiki ke ho'ākāka 'ia ma wale puni ia i ka iieeaii, ao kona aoao a me ka pana pua e like i kekahi i kekahi, i mea, a puni ka equilateral triangle, heʻahā like, rhombus, etc. akau E hoʻoponopono i kēia pilikia ia mea pono e imi i ke anapuni o ka iieeaii, a make mai o kona lima, a me ka wahi. Nolaila, mākaukau i ke alii, panana, me ka m'kini helu, a me ka puke noke me ka peni.

Pehea e loaʻa i ka ke kahahńnai o ka p ÷ ai, ina ka mea, ua ho'ākāka 'ia e pili ana i ka triangle

Haʻilula 1: R = (A * B * B) / 4S, ma A, B, C, - lōʻihi o ka triangle aoao, a me S - kona wahi.

Haʻilula 2: R = A / hewa i kekahi, kahi A - ka lōʻihi o kekahiʻaoʻao o ka huahelu, a me ka hewa a me ka - he mau hōʻailona i waiwai o ka sine o ka huinaʻaoʻao e ku pono ana.

Ke kahahńnai o ka p ÷ ai i ho'ākāka 'ia a puni ka akau-huina triangle.

Haʻilula 1: R = B / 2, ma B - hypotenuse.

Haʻilula 2: R = M * B, ma B - hypotenuse, a me M - i ka Media hana ia mea.

Pehea e loaʻa i ka ke kahahńnai o ka kaiapili ina mea ua ho'ākāka 'ia a puni ka mau iieeaii

Haʻilula: R = A / (2 * hewa (360 / (2 * N))), kahi A - ka lōʻihi o kekahiʻaoʻao o ka huahelu, a me N - ka helu o ka aoao ma ka geometrical huahelu.

Pehea e loaʻa i ka ke kahahńnai o ka incircle

Ua kapaʻia ka mea kākauʻia kaiapili ka wā e pili ana i nāʻaoʻao o ka iieeaii. E noonoo oe i kekahi mau examples.

Haʻilula 1: R = S / (P / 2) kahi - S a me R - i ka wahi a me ka anapuni o ka huahelu pakahi.

Haʻilula 2: R = (P / 2 - A) * tg (i / 2), ma P - anapuni A - lōʻihi o kekahi o na aoao elua, a - ku pono ana i kēiaʻaoʻao o ka huina.

Pehea e loaʻa i ka ke kahahńnai o ka p ÷ ai, ina ka mea, ua kākauʻia i loko o ka triangle akau

Haʻilula 1:

Ke kahahńnai o ka p ÷ ai i ua kākauʻia i loko o ka rhomb

A kaiapili hiki ke kākauʻia i loko o kekahi rhombus mea he equilateral a me ka scalene.

Haʻilula 1: R = 2 * H, kahi H - ke kiekie o ka geometric shape.

Haʻilula 2: R = S / (A * 2), kahi S - o ka wahi o ka rhombus, a me ka A -ʻaoʻao o kona lōʻihi.

Haʻilula 3: R = √ ((S * hewa A) / 4), kahi S - o ka wahi o ka rhombus, a me A hewa - sine huʻi huina o ka geometrical huahelu.

Haʻilula 4: R = V * T / (√ (V² + G²) kahi B a me T - o ka lōʻihi o nā diagonals o ka geometrical huahelu.

Haʻilula 5: R = B * hewa (A / 2), ma - ka diagonal o ka rhombus, a me ka A - o ka huina ma ka vertices e hoʻohui i ka diagonal.

Ke kahahńnai o ka p ÷ ai i ua kākauʻia i loko o ka triangle

I ka hanana i loko o ka pilikia i haawi mai ai oe i ka lōʻihi o nāʻaoʻao o ka huahelu, mua e huli i ke anapuni o ka triangle (U), a laila, hapa-anapuni (N):

P = A + B + C, ma A, B, - i ka lōʻihi o nāʻaoʻao o ka geometric huahelu.

N = N / 2.

Haʻilula 1: R = √ ((P-A) * (N-D) * (N-B) / N).

A ina, e ike ana a pau o na ia ekolu aoao elua, i oe haawiia hou a me ka wahi o ka huahelu, e hiki e huli i ka makemake huahelu like penei.

Haʻilula 2: R = S * 2 (A + B + C)

Haʻilula 3: R = S / [illegible] = S / (A + B + C) / 2), kahi - N - Ua semiperimeter geometric huahelu.

Haʻilula 4: R = (N - k) * tg (A / 2), kahi N - Ua semiperimeter triangle A - kekahi o kona aoao, a me ka tg (A / 2) - tangent o ka hapalua o kēiaʻaoʻao o ka mea ku pono huina.

A ma lalo o ka luna haʻilula e loaʻa i ka ke kahahńnai o ka p ÷ ai i ua kākauʻia i loko o ka equilateral triangle.

Haʻilula 5: R = A * √3 / 6.

Ke kahahńnai o ka p ÷ ai i ua kākauʻia i loko o ka triangle akau

Inā he pilikia i haawiia i ka lōʻihi o nā wāwae, a me ka hypotenuse, alaila, o ka ke kahahńnai o ka kākauʻia kaiapili me ka 'ike.

Haʻilula 1: = (A + B-C) R / 2, kahi A a me B - nā wāwae, C - hypotenuse.

Ma ia hihia, ina oe e wale nā wāwae, ka mea, ka manawa e hoomanao i ka Pythagorean theorem, e imi i ka hypotenuse, a, e hoʻohana i ka luna haʻilula.

C = √ (A² + B²).

Ke kahahńnai o ka p ÷ ai i ua kākauʻia i loko o ka huinahalike

E kahalina i ua kākauʻia i loko o ka huinahalike, i hookaawale ai i kona 4 aoao pono ka hapalua o na mea nui o ke tangency.

Haʻilula 1: R = A / 2, kahi A -ʻaoʻao lōʻihi o ka huinahalike.

Haʻilula 2: R = S / (P / 2), kahi S a me F - i ka wahi a me ka anapuni o ka huinahalike, niioaaonoaaiii.
