First , find the circumference of the wheel :-
= Pi times diameter
= Pi times 98
= 22/7 times 98
= 2516/7
= 308
Then, you divide the total distance by the circumference to get the rotations:-
= 1540 / 308
= 5
Thus, the number of rotations is 5

Find the radius:
Radius = Diameter ÷ 2
Radius = 98 ÷ 2 = 49 cm
Find one revolution:
One revolution = 2πr
One revolution = 2π(49)
One revolution = 308 cm
Find the number of revolutions needed to cover 1540 m:
one revolution = 308 cm
Number of revolutions needed = 1540 ÷ 308 = 5
Answer: 5 revolutions
