3 pahiye ki paridhiye 50 cm 60 cm aur 90 cm hai kam se kam kitni duri chalne ke baad tino pahiye ak sath chakar lagayenge

Answer 1

Answer:

वह दूरी 2π×50 , 2π×60 और 2π×90 के लघुतम के बराबर होगी

50 = 2 × 5 × 5

60 = 2 × 2 × 3 × 5

90 = 2 × 3 × 3 × 5

अतएव लघुतम = 2 × 2 × 3 × 3 × 5 × 5 = 900

दूरी =

$= 2\pi \: r \\ = 2 \times \frac{22}{7} \times 900 \\ = 5652 \: cm$
