How kuwana nharaunda ine denderedzwa: kubatsira vadzidzi

How kuwana nharaunda yacho denderedzwa? mubvunzo uyu anogara kukosha vadzidzi kudzidza planimetry. Below tinotarisa mienzaniso sei unogona kukurira basa.

Zvichienderana nharaunda yacho denderedzwa basa ezvinhu, unogona kuwana nzira.

Formula 1: R = L / 2π, apo A - ndiko kuti sekamufarenzi, uye π - chenguva yakaenzana 3.141 ...

Formula 2: R = √ (S / π), apo S - ndiyo uwandu nzvimbo denderedzwa.

Formula 3: R = D / 2 apo D - ndiko kuti dhayamita ari denderedzwa, i.e. nokureba chikamu iyo, achipfuura nechepakati mufananidzo rinobatanidza maviri maximally munzvimbo dzokuzororera dzaiva kunze points.

How kuwana nharaunda yacho circumcircle

Ngatitangei rinotsanangura izwi pachayo. Sekamufarenzi achinzi akarondedzera kana chokuita zvose polygon vertices. Zvinofanira kucherechedzwa kuti denderedzwa inogona kurondedzerwa dzakapoteredza polygon akadaro, ane mativi uye pamakona vakaenzana mumwe chete, kureva kuti, kumativi ane equilateral Triangle, mativi, rhombus, etc. kurudyi Kugadzirisa dambudziko iri zvakafanira kuwana mukomberedzo ane polygon, uye akafa muruoko rwake uye nzvimbo. Saka, aine mutongi, kambasi, karukureta, uye mukabhuku pamwe chinyoreso.

How kuwana nharaunda yacho denderedzwa, kana chinorondedzerwa pamusoro netriangle

Formula 1: R = (A * B * B) / 4S, apo A, B, C, - kureba Triangle mativi, uye S - ayo nharaunda.

Formula 2: R = A / chivi a, apo A - pakureba rumwe rutivi nechipi, uye chivi uye - munhu akaverenga kukosha Sine nevakomana angled divi.

The nharaunda yacho denderedzwa zvinorondedzerwa kunhivi Triangle kodzero-angled.

Formula 1: R = B / 2, apo B - hypotenuse.

Formula 2: R = M * B, apo B - hypotenuse, uye M - muMedhia akapiwa inoitwa kwazviri.

How kuwana nharaunda ine denderedzwa kana chinorondedzerwa kumativi nguva polygon

Formula: R = A / (2 * chivi (360 / (2 * n))), apo A - pakureba rumwe rutivi nechipi, uye N - Nhamba kumativi ari geometrical nhamba.

How kuwana nharaunda yacho incircle

Rakanyorwa denderedzwa unonzi kana pachirehwa kumativi ose polygon. Funga nezvemienzaniso mishoma.

Formula 1: R = S / (P / 2) apo - S uye R - nzvimbo uye mukomberedzo yacho nechipi azvaitwa.

Formula 2: R = (P / 2 - A) * c nkm (a / 2), apo P - mukomberedzo A - pakureba mumwe vemapato, uye - pakatarisana rwuno pakona.

How kuwana nharaunda yacho denderedzwa, kana akanyorwa netriangle zvakanaka

Fomura 1:

The nharaunda yacho denderedzwa iri rakanyorwa muna rhomb

A denderedzwa chinogona akanyorwa chero rhombus chinhu equilateral uye scalene.

Formula 1: R = 2 * H, apo H - kukwirira geometric chimiro.

Formula 2: R = S / (A * 2), apo S - ndiyo nzvimbo yacho rhombus, uye A - divi kureba kwayo.

Formula 3: R = √ ((S * chivi A) / 4), apo S - ndiyo nzvimbo yacho rhombus, uye A chivi - Sine rikwanise pakona yacho geometrical nhamba.

Formula 4: R = V * T / (√ (V² + G²) apo B uye T - ndiye pakureba diagonals ari geometrical nhamba.

Formula 5: R = B * chivi (A / 2), apo - the diagonal of rhombus, uye A - ndiye pakona panguva vertices kuti kubatanidza diagonal.

The nharaunda yacho denderedzwa iri rakanyorwa muna Triangle

Kuri kuti iri dambudziko yauri kupiwa urefu panhivi nechipi, tanga ngaaverenge mukomberedzo yacho Triangle (U), uye ipapo hafu-mukomberedzo (n):

P = A + B + C, apo A, B, - kureba kwakaita mativi geometric nhamba.

n = n / 2.

Formula 1: R = √ ((p-A) * (n-D) * (n-B) / n).

Uye kana, achiziva zvose zvakafanana vemapato matatu, iwe vakapiwa uye nzvimbo nechipi, unogona ngaaverenge aida siyana sezvinotevera.

Formula 2: R = S * 2 (A + B + C)

Formula 3: R = S / F = S / (A + B + C) / 2), apo - N - iri semiperimeter geometric mufananidzo.

Formula 4: R = (n - k) * c nkm (A / 2), apo N - iri semiperimeter netriangle A - mumwe kumativi acho, uye nkm (A / 2) - tangent hafu rwuno nevakomana yorusvingo.

A pazasi pamusoro payakavakirwa uchawana nharaunda yacho denderedzwa iri akanyorwa ane equilateral Triangle.

Formula 5: R = A * √3 / 6.

The nharaunda yacho denderedzwa iri nokudhindwa Triangle zvakanaka

Kana dambudziko kupiwa pakureba makumbo uye hypotenuse, ipapo nharaunda yacho yakanyorwa denderedzwa sezvo iri kuzivikanwa.

Formula 1: R = (A + B-C) / 2, apo A uye B - makumbo, C - hypotenuse.

Pakadaro, kana muri chete gumbo maviri, yava nguva kuyeuka Pythagorean theorem no kuwana hypotenuse uye kushandisa pamusoro payakavakirwa.

C = √ (A² + B²).

The nharaunda pamusoro denderedzwa iri nokudhindwa sikweya

Denderedzwa iri nokudhindwa sikweya, rinokamukana dzose 4 panhivi chaizvo hafu zvakatinakidza tangency.

Formula 1: R = A / 2, apo A - divi Kureba sikweya.

Formula 2: R = S / (P / 2), apo S uye F - nzvimbo uye mukomberedzo ane sikweya, ukuwo.
