Kodi circumference

Ife kawirikawiri ntchito ndi zithunzi zojambula pa zomwe anapezazo tikutsutsa kufotokoza mosavuta. Ngati mukufuna kupeza malo a apakati kapena rectangle, iwo akhoza kugawidwa mu zina ndi kubweretsa chilinganizo bwino intuitively. Komabe, kutalika kwa bwalo - ndithu muyezo chinthu ophunzira wamba. Nthawi zambiri pali kusadziwa nkhaniyi. Tiyeni tiwone chomwe chiri cholakwika.

Bwalo yokha aumbike mwa magawo awiri; utali wozungulira ndi zojambula malo a pakati. Last odziwa sekondale, kotero ife alibe chidwi izo. Koma poyamba amapereka katundu pamoyo monga lalikulu. Circumference kwenikweni zimadalira yekha utali wozungulira imaŵerengedwa monga mwa chilinganizo zotsatirazi:

L = 2np

Kuti chithunzi anakhumba L. kuvomereza Modifier P ( "ku Pihahiroti") nthawi zonse. Kuti bwinobwino kuthetsa mavuto kusukulu mokwanira kudziwa kuti P = 3,14. Komabe, si nthawi zonse zofunikira m'malo mtengo uwu, chifukwa ndi simplistic kwambiri. Pankhani mwaunyinji, m'pofunika kuganizira ambiri ndithu malo decimal. Choncho, nthawi zambiri, ndi yankho zambiri cholandirika Tinganene popanda nazo iliyonse. Onani kuti mawerengedwe circumferential kutalika zimatengera yekha utali wozungulira wa. Ndi muyeso wa mmene kutali mfundo zonse za bwalo ku likulu. Choncho, chizindikiro ichi ndi kuposa yaitali Arc lapansi. Monga zokhazikitsidwa mwachizolowezi mtunda, L amayezedwa meters. R - utali wozungulira.

Mu mawu zambiri zothandiza pali ntchito yovuta. Mwachitsanzo, pamene chofunika kutalika Arc chozungulira. Apa pang'ono zovuta chilinganizo. Iwo ayenera kumvetsa kuti zachokera chitsanzo zofunika, koma inu kudula gawo zosafunika wa utali. Mu mau, akhoza kulemba monga:

L = 2np / 360 * N

Monga mmene taonera, panali wina watsopano variable N. Izi ndi umboni wosatsutsika. The circumference lonse unagawidwa madigiri 360. Choncho, anadziwika mmene mamita ambiri digiri 1. Komanso, m'malo kuchiyambi anakhumba padziko olamulira m'malo kalata N, ife kutenga nthawi yaitali yankho. Kutenga unit gawo, tili mogwirizana ndi nthawi zake kuchuluka N.

Kodi mukufuna kudziwa moyo weniweniwo, kodi circumference? Funso sangathe kupereka yankho, amene alalikira m'madera onse a ntchito. Koma kuyamba ndi kuona maola achikale. Kudziwa osiyanasiyana zoyenda m'manja chachiwiri, n'zotheka kupeza mtunda kuti ali kupita mu miniti. Pambuyo kuzindikirike njira ndi nthawi, tingapeze changu chimene limayenda. Ndiyeno nda kwambiri anthu a maola. Ngati wopalasa njinga ikuyenda pa njanji zozungulira, kuyenda ake nthawi amadalira liwiro ndi utali wozungulira. Mungapeze ndi mathamangitsidwe ake. Mu makina ochapira si popanda index, lomwe ife pafupifupi ankaiphwasula. Pali circumferential kutalika zofunika kuwerenga kusintha (onse Ndipotu apuma pa mtunda), anachita kwa muyezo winawake wa nthawi. Kumbali womwalira chifukwa kutalika circumferential wa zoyenda ananeneratu ya mapulaneti m'njira ndi zina zotero.

Choncho, kumvetsa bwino nkhani m'pofunika kukumbukira mitunduyi awiri okha. kudziwa Ichi chidzakhala zothandiza kwa inu osati sukulu kubera, komanso moyo weniweniwo.
