Hiiii.....
No. of rotation = Distance / 2 pie r ......
d = 70 ... r = 35 cm ...
In metre ... r = 0.35 ....
n = 3.3 × 1000 / 2 × 3.14 × 0.35 ...
.... n = 1501.36 ......rotation....

Hello Dear...
parimeter of wheel =2πr = (2×22×70)/7×2 = 3080/14 = 220cm =220/100000= 0.0022km
Given distance = 3.3km
wheel will rotate to cover the distance = 3.3/0.0022 = 1500 rounds
Thankyou Buddy...
