Okuqukethwe
Ngemva kokunquma ukudweba isitsha noma ukubeka itshe lomgwaqo endaweni eyindilinga, ukubala inani lezinto ezibonakalayo, udinga ukwazi umjikelezo. Ngokusebenzisa umshini wokubala we-inthanethi ukubala umjikelezo wombuthano, uzothola imiphumela enembile ngokushesha.
Circle – ijika elihlanganisa amaphuzu alinganayo ukusuka enkabeni endizeni, ephinde ibe yipherimitha.
Ububanzi – ingxenye esuka enkabeni iye kunoma iyiphi indawo embuthanweni.
ububanzi ingxenye yomugqa phakathi kwamaphoyinti amabili endingilizini edlula phakathi nendawo.
Ungakwazi ukubala ukuzungeza kwesiyingi ngobubanzi noma irediyasi.
Ifomula yokubala ubude ngobubanzi:
L= πD
kuphi:
- L - ukuzungeza;
- D - ububanzi;
- π - 3,14.
Ububanzi
Uma irediyasi yaziwa, khona-ke sinikeza isibali sokubala isiyingi (umjikelezo) ngerediyasi.
Kulokhu, ifomula ibonakala kanje:
L=2πr
kuphi: r iyindawo engaba yindilinga.
Ukubalwa kobubanzi
Ngezinye izikhathi kuyadingeka, ngokuphambene, ukuthola ububanzi kusuka kumjikelezo. Ungasebenzisa isibali se-inthanethi esihlongozwayo kulezi zibalo.
