Mubwana, twabaruye kare usibye mumasomo yimibare. Mubuzima bukuze bukenewe, duhura nabyo iyo dusabye, turateganya gushyiramo ibikoresho cyangwa twemera inzu yumuyiyeya.
"Fata kandi ukore" werekana uburyo bwo kubara neza agace k'imiterere rusange ya geometric: urukiramende, kare, uruziga, inyabutatu na trapezium.
Nigute Kubara Agace ka Urukiramende
Kubara aho urukiramende, ugomba kugwiza uburebure bwishusho kubugari. Dufate ko dupima agace k'icyumba. Nim00 m, kandi mubugari - m 3. Ndagwije imyaka 6 kugeza 3 mbone umwanya wucyumba - metero kare 18. m.
Nigute ushobora kubara kare kare
Agace ka kare kabazwe muburyo busa: uburebure bwacyo buragwira nubugari. Ariko, nkuko tubizi, ababuranyi bangana kuri mugenzi wabo. Kubwibyo, formula imanuka mukubaka umwe mubaburanyi kuri kare.
Nigute Kubara Agace k'uruziga
Gato yo kubara akarere k'uruziga. Kugira ngo ukore ibi, ugomba kumenya radiyo yayo, bingana na kimwe cya kabiri cya diameter. Diameter ubwayo ni igice gihuza amanota 2 kuruziga no kunyura hagati yacyo. Kubara ako gace, gupima diameter hanyuma ukune ibisubizo byabonetse na 2. ✅ Uruziga rwa Forge Uruziga rusa nkiyi: Dufata umubare wa 3.14) kandi tugwiza Radius muri kare. Biracyahari kwibuka ko ibisubizo byimibare bitazaba byukuri rwose, kubera ko umubare PI ifite agaciro kagereranijwe. Dufate ko tubarira agace k'ibisenge by'ibisimba munsi ya chandelier. Banza upima diameter yayo. Reka bingana na 0.46 m. Tuyigabanye kugeza 2 tukabona agaciro ka radiyo ya 0.23. Tuzukwa muri kare: 0.23 * 0.23 * 0.23 = 0.0529. Noneho kugwira numubare PI: 3.14 * 0.0529 = 0.1661. Kubwibyo, ahantu hatagaragara ni metero kare 0.1661. m.
Nigute Kubara Agace ka mpandeshatu iburyo
Kubara agace ka mpandeshatu cyangwa iringaniye - Igikorwa kiragoye cyane. Fortala irasa gutya: Imizi ya kare ya 3 igabanijwemo 4 kandi igwira nuburebure bwimpande imwe muri kare. Tworoshya igice cya mbere: Imizi ya kare ya 3 ifite hafi 1.732. Tugabanye ibisubizo na 4, tubona hafi 0.433. Iyi mibare ni igice gihoraho cya formula. Noneho dufata uburebure bwimpande (reka bingana na cm 20), tuzukwa muri kare kandi tugwiza na 0.433. Twabonye agace - 173.2 habaho metero kare. cm.
Nigute ushobora kubara agace ka mpandeshatu
Hamwe na mpandeshatu, ibintu byose biroroshye: kugwiza 1/2 kumurimo winyama zayo (amashyaka yegeranye no kwerekeza). Kurugero, niba kuruhande rwa mpandeshatu ari cm 6, kandi hepfo ni cm 4, hanyuma akarere kayo tuba tubara: 1/2 (6 * 4) = 12 KV. cm.
Nigute ushobora kubara kare ya trapez
Kugirango ubone agace ka trapezium, gabanya uburebure bwacyo muri 2 no kugwiza umubare wimpande. Kurugero, niba uburebure bwa Trapezium ari cm 4, kuruhande rwa cm 3, kandi hepfo ni cm 6, hanyuma ukurikije form: H / 2 (B1 + B2) kubara akarere ka Igishushanyo gisa nkiyi: 4/2 (3 + 6) = 2 * 9 = 18.
