How kuverenga dhayamita of denderedzwa?

For Mutange, ngationei chii denderedzwa uye rakasiyana sei kubva denderedzwa. Tora chinyoreso kana penzura uye tsvuku pendi pamusoro kapepa nguva denderedzwa. Kupenda rose pakati zvichizoita ndeuke yebhuruu penzura. Red pepa rehurukuro inotaridza chimiro pamuganhu - denderedzwa. Asi zviri rebhuruu mukati - uye pane denderedzwa.

The kukura denderedzwa uye denderedzwa dhayamita kwakatemwa. On tsvuku mutsetse chokuguma denderedzwa, mutarisise mbiri pfungwa kuitira kuti vaiva girazi mifananidzo mumwe. Peya navo mutsetse. The chidimbu unofanira kupfuura nomunyika pana nepakati denderedzwa. chidimbu ichi unobatanidza pakatarisana zvikamu denderedzwa, uye inonzi dhayamita geometry.

Chidimbu kuti kwete anomanyira nepakati denderedzwa, asi merges nevakomana kumigumo anonzi Chord. Somugumisiro, Chord anomhanya nepakati pfungwa denderedzwa, uye ayo dhayamita iri.

Runotaurwa dhayamita Latin tsamba D. Kuwana dhayamita pamusoro denderedzwa anogona kuva netsika dzakadai nharaunda, urefu uye nharaunda yacho denderedzwa.

Kure kubva pakati pfungwa kusvikira pamusoro sekamufarenzi kunonoka, akadana nharaunda uye zvinoratidzwa tsamba R. The ruzivo nharaunda yacho denderedzwa dhayamita kunobatsira kuti compute iri nyore kuita:

D = 2 * R

. Somuenzaniso, nharaunda - 7 masendimita 7 masendimita muwande ne 2 uye kuwana kukosha zvakaenzana 14 CM A: D akaenzana akafanorongerwa dimikira masendimita 14 ..

Dzimwe zvakafanira kuona dhayamita ane denderedzwa pamwe kureba kwayo. Pano zvakafanira kushandisa nzira chaiyo inobatsira kuziva kuti sekamufarenzi. Mukana wokuti vanhu vanga 2 L = Pi * R, apo 2 - Ndinoramba ukoshi (kugara), uye Pi = 3.14. Uye sezvo zvinozivikanwa kuti R = D * 2, zvino nzira inogona kumiririrwa neimwe nzira

L = Pi * D

D = L / Pi

Mashoko aya anoshandisa nzira denderedzwa dhayamita. Dzinomiririra known kukosha mune dambudziko kugadzirisa munhu mukana wokuti vanhu vanga pamwe chete USINGAZIKAMWI. Kufunga kureba 7 M Naizvozvo .:

D = 7/3, 14

D = 21, 98

A: dhayamita pamusoro 21,98 mamita.

Kana kukosha nzvimbo chikazozikamwa, zvingadarowo kuona dhayamita yacho denderedzwa. The yemaitiro rinoshandiswa hazvisi sezvinotevera:

D = 2 * (S / PI) * (1/2)

S - iyi kana nzvimbo yacho nhamba. Somuenzaniso, mune basa nayo akaenzana 30 mativi mamita. M. We kuwana:

D = 2 * (30/3, 14) * (1/2) D = 9 55414

Kana akasarudzwa basa iri nokukura akaenzana vhoriyamu (V) ari bhora, zvinotevera payakavakirwa huri dhayamita: D = (6 V / PI) * 1/3.

Dzimwe nguva unofanira kuwana dhayamita ane denderedzwa nokudhindwa Triangle. Nokuti chinangwa ichi, maererano nzira anomirirwa denderedzwa nharaunda kuwana:

R = S / p (S - akafanorongerwa nzvimbo Triangle, uye peji - mukomberedzo yakakamurwa 2).

Mugumisiro kaviri, tichifunga kuti D = 2 * R.

Kazhinji kuwana denderedzwa dhayamita uye vane musha. Somuenzaniso, apo kuziva kukura mhete, inova yakaenzana kwayo dhayamita. Kuti aite izvi, putira nomunwe munhu zvinogona muridzi shinda mhete. Mark pfungwa kunyorerana yacho miviri. Kuyera Kureba mutsetse kubva nguva kukuratidza. The zvichiguma ukoshi zvikawanda ne 3.14, vachitevera nzira nokuda kuziva dhayamita munhu anozivikanwa urefu. Saka, mashoko okuti ruzivo geometry uye nemasvomhu muupenyu isinakukodzera, havasi anoenderana chokwadi. Uye chikonzero chakakura kutora mamwe basa zvidzidzo chikoro.
