Pie ka ek tukda

Pie chart tukdon mein kata ek vritt hai, jaise ghar mein bata hua pie. Har tukda poore ke ek hisse ko dikhaata hai, aur hissa jitna bada, tukda utna bada. Kyunki poora vritt 360° ghoomta hai, har tukde ke centre ka kon us hisse ke samaanupaati hona chahiye. Isliye pie chart, poore ko diye gaye anupaat mein baantne ka ek badhiya upyog hai.

Kon nikaalna

Book ke udaaharan mein 40 students aur unke grades hain:

GradeABCDE
Students1210864

Isliye 360° ko 12 : 10 : 8 : 6 : 4 mein baantna hai. Pehle saral karo. Paanchon sankhyaon ka HCF 2 hai, isliye anupaat 6 : 5 : 4 : 3 : 2 ban jaata hai. Ye 6 + 5 + 4 + 3 + 2 = 20 hisse hain, aur ek hissa 360° ÷ 20 = 18° hai. Isliye grade A ko 6 × 18° = 108°, B ko 90°, C ko 72°, D ko 54° aur E ko 36° milta hai. Jaanch ke liye jodo: 108 + 90 + 72 + 54 + 36 = 360.

Aam niyam hai kon = (hissa ÷ kul) × 360°. Pratishat ke liye aur bhi aasaan: vritt ka 1% = 3.6°, isliye 50% = 180°, 25% = 90°, 15% = 54° aur 10% = 36°.

  1. Compass se vritt banao aur ek radius, AB, kheencho.
  2. Protractor ka centre A, yaani vritt ke centre, par aur uska aadhaar AB par rakho. 108° naapo (book ki tarah ghadi ki ulti disha mein) aur nayi radius AC kheencho. Ye tukda grade A hai.
  3. AC se 90° naapo aur grade B ke liye AD kheencho.
  4. AD se 72° naapo aur grade C ke liye AE kheencho.
  5. 54° (D) aur 36° (E) ke liye aise hi karo. Aakhri tukda theek AB par khatm hona chahiye.
  6. Har tukde ko rang do, naam likho, aur chart ko title do.

Naapne ki chhoti galtiyaan ghoomte-ghoomte jud jaati hain, isliye har kon usse theek pehle kheenchi rekha se dhyaan se naapo.

Pie chart padhna

Pie chart ulta bhi padha ja sakta hai. Bachche school kaise aate hain, is survey mein tukde hain bus 120°, paidal 90°, cycle 60° aur two-wheeler 60°, aur car ka tukda bacha hua hai: 360° − 330° = 30°. Bus ka tukda sabse bada, vritt ka ek-tihaai, hai, isliye bus sabse aam saadhan hai. Car ka tukda 30° ÷ 360° = 1/12 bachche hain. Agar 18 bachche car se aate hain, to survey mein 18 × 12 = 216 bachche the, aur 90° ka paidal tukda unka ek-chauthaai, 54 bachche, hai. Cycle aur two-wheeler ke tukde barabar hain, isliye barabar bachche unse aate hain.
