r = 42 \: cm \\c = 2 \times \pi  \times \: r \\  = 2 \times 22  \times  \frac{22}{7}   \\  = 22 \times 2 \times 6 \\  = 264 \: cm

distance \: travelled \: in \: 400 \: rolls = 264 \times 400 \\  = 105600 \: cm \\ if \: we \: write \: 105600 \: cm \: in \: m =  \frac{105600}{100} \\  = 1056  \:  \:  \:  \:  \:  \: (because \: 1 \: m = 100 \: cm ) \\ thus \: the \: wheel \: would \: cover \: 1056 \: m \: in \: 400 \: revolutions

Given :  42 cm त्रिज्या वाले पहिए द्वारा 400 चक्कर

To Find : दूरी

Solution:

1 चक्कर   में   दूरी  = 2 π * त्रिज्या

= 2 * (22/7) * 42

= 44 * 6

=  264  cm

400 चक्कर  में   दूरी  = 400  * 264  cm

= 400 * 264 / 100  m

= 4 * 264 m

=  1056 m

एक 42 cm त्रिज्या वाले पहिए द्वारा 400 चक्कर लगाने में   1056 m  दूरी
