Step-by-step explanation:
700 revolutions. We know that in 1 revolution, wheel will cover a distance equal to its circumference. So mathematically, in one revolution, it travels 131.88 cms. Now the wheel has to travel 924 m which is equivalent to 92400 cms. So, we need to simply find the number of revolutions. Just like in marketing there is formula : Qty = Cost/Rate, similarly, we divide distance that has to be traversed by wheel with the distance traversed by wheel in one revolution to find number of revolutions. You will find it in decimal. So round it off until decimal gets removed by rules and regulations and you'll get this answer. Hope this helps...

Answer:
Radius = 4.5 feet
After travel 20 rotations, the distance covered
= 2*3.14*4.5
= 28.26 feet
