Question

Ek pahiye ka Vyas 70 sentimeter Hai 66 kilometre mein vah kitne Chakkar Lagaya jaega​

Answer 1

Step-by-step explanation:

66km = 6600000 cm

distance covered in 1 revolution = (22÷7)70 = 220cm

No. of revolution = 6600000 ÷ distance covered in 1 revolution

No. of revolution = 6600000 ÷ 220 = 30000

Answer 2

$diameter = 70cm \\ radius = 35cm = 0.35m \\ cirumfrence \: of \: the \: circle = 2\pi \: r \\ = 2\times \frac{22}{7} \times 0.35 \\ = 22{m}^{2} \\ rounds \: in \: 66 \: km = \\ = \frac{66 \times 1000}{22} \\ = 3 \times 1000 \\ = 3000 \\ hence \: in \: 66km \: it \: rotate \: 3000 \: times$
