Sida loo helo gacan ku goobada: in lagu caawiyo ardayda

Sida loo helo gacan ku goobada? Su'aashani waxay had iyo jeer waa muhiim u ah ardayda wax ka barata planimetry. Hoos aynu eegno tusaalooyin ka mid ah sida aad ula qabsan kartaa hawsha.

Iyadoo ku xiran gacan ka mid ah xaaladaha hawsha goobada, waxaad ka heli kartaa hab.

Formula 1: R = L / 2π, halkaas A - waa goobada ah, iyo π - joogto ah loo siman yahay si 3,141 ...

Formula 2: R = √ (S / π), halkaas oo S - waa xaddiga lacagta ee bedka goobada.

Formula 3: R = D / 2 meesha D - waa dhexroorka goobada, i.e. dhererka qaybta kaas oo, marayay bartamaha tiradaasi xiriirisa laba dhibcood maximally kullan gooni.

Sida loo helo gacan ku of circumcircle ah

First aynu qeexo ereyga laftiisa. Goobada la yiraahdo tilmaamay marka ay ku saabsan tahay oo dhan geesaha geesoolayaasha. Waa in la ogaadaa in goobo lagu tilmaami karaa oo kaliya ku dhawaad geesoolayaasha noocan oo kale ah, kuwaas oo dhinac iyo xaglaha waa u siman yihiin in ay midba midka kale, in uu yahay, ku dhawaad saddex xagalka isle ah, oo laba jibbaaran, rhombus, iwm xaq u Si loo xalliyo dhibaatada this waxaa lagama maarmaan ah in la helo wareega geesoole, oo ay dhinteen gacantiisa iyo aagga. Sidaa darteed, ku hubaysan taliye, wareegtaan, calculator, oo buug qalin la.

Sida loo helo gacan ku goobada, haddii la tilmaamay oo ku saabsan saddex xagalka ah

Formula 1: R = (A * B * B) / 4s, halkaas A, B, C, - cimri dhinac saddexagalka, iyo S - deegaankeeda.

Formula 2: R = A / dembi ah, halkaas oo A - dhererka hal dhinac oo ah tiradaasi, iyo dembiga iyo - qiimaha xisaabiyaa of Culumida Soomaaliyeed ee dhinaca xagal ka soo hor jeedda.

gacan The of goobada ku tilmaamay agagaarka xagal-xagal midig.

Formula 1: R = B / 2, halkaas oo B - shakaal.

Formula 2: R = M * B, halkaas oo B - shakaal, iyo M - bartamaha sameeyay daraa.

Sida loo helo gacan ku goobada haddii la tilmaamay agagaarka geesoolayaasha joogto ah

Formula: R = A / (2 * dembiga (360 / (2 * n))), halkaas oo A - dhererka hal dhinac oo ah tiradaasi, iyo n - tirada dhinac shaxanka joomatari.

Sida loo helo gacan ku of incircle ah

Wareegga Isasaaray waxaa loo yaqaan marka ay khusaysaa dhammaan dhinacyada geesoolayaasha ah. Tixgeli dhowr tusaale.

Formula 1: R = S / (P / 2) halkaas - S iyo R - ee bedka iyo wareega ah tiradaasi ay u kala horreeyaan.

Formula 2: R = (P / 2 - A) * tg (a / 2), halkaasoo P - wareega A - dhererka mid ka mid ah dhinacyada, iyo - soo horjeeda kooxda this of xagal.

Sida loo helo gacan ku goobada, haddii la qoro saddex xagalka toosan

Formula 1:

gacan goobada oo lagu qoro rhomb ah

goobaabin A la Isasaaray karaa rhombus kasta waa isle iyo scalene.

Formula 1: R = 2 * H, halkaas oo H - height of qaabka joomateri.

Formula 2: R = S / (A * 2), halkaas oo S - waa meesha of rhombus ah, iyo A - side ah oo dhererkiisu.

Formula 3: R = √ ((* dembi S A) / 4), halkaas oo S - waa meel ka mid ah rhombus ah, iyo Dambi A - xagal Culumida ba'an ee tiradaasi joomatari.

Formula 4: R = V * T / (√ (V² + G²) halkaas oo B iyo T - waa dhererka ka diagonals of tiradaasi joomatari.

Formula 5: R = dembi * B (A / 2), halkaasoo ah - dadab ah rhombus ah, iyo A - waa xagal ee geesaha ah kuwaasi oo ku xidha dadab ah.

gacan goobada oo lagu qoro saddexagalka

Haddii ay dhacdo in in dhibaatada lagu siiyo dheer oo ka mid ah dhinacyada tiradaasi, marka hore xisaabi ah wareegga kore ee saddexagalka (U), ka dibna bar-wareega (n):

P = A + B + C, halkaasoo A, B, - dheer dhinac ee tiradaasi joomateri.

n = n / 2.

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

Oo haddii, isagoo garanaya oo dhan isku mid ah saddexda xisbi, waxa la siiyaa aad wax dheeraad ah oo aagga ah tiradaasi, aad xisaabi kartaa kala duwan oo la doonayo sida soo socota.

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

Formula 3: R = S / f = S / (A + B + C) / 2), halkaasoo - n - Waa tiro joomateri semiperimeter.

Formula 4: R = (n - k) * tg (A / 2), halkaas oo n - waa xagalka semiperimeter A - mid ka mid ah dhinac, iyo tg (A / 2) - Taabte ee qeybta dhinacan of xagal ka soo horjeeda.

A hoos formula ee kor ku xusan ka heli doontaa gacan goobada oo lagu qoro xagalka ah isle.

Formula 5: R = A * √3 / 6.

gacan goobada oo lagu qoro xagalka toosan

Haddii wax dhibaato ah la siiyo dhererka lugaha iyo shakaal, markaas gacan ka mid ah goobada Isasaaray sida la aqoonsan yahay.

Formula 1: R = (A + B-C) / 2, halkaas oo A iyo B - lugaha, C - shakaal.

Haddii ay sidaa tahay, haddii aad laba lugta oo kaliya waa, waxa la joogaa wakhtigii si ay u xusuusan Aragtida ku Theorem si aad u hesho shakaal iyo in ay isticmaalaan caanaha ee kor ku xusan.

C = √ (A² + B²).

gacan ee goobo la qoro square ah

Circle kaas oo la qoro square ah, kala qaybinaya oo dhan 4 kooxood ay si sax ah qeybtii dhibcood tangency.

Formula 1: R = A / 2, halkaas oo A - dhererka dhinac oo square ah.

Formula 2: R = S / (P / 2), halkaas oo S iyo F - ee bedka iyo wareega of square ah, siday u kala horreeyaan.
