Answer :-
The number of revolves to cover 99m is 50 revolutions.
Step-by-step explanation :-
To Find,
- Number of times the wheel will revolve to cover a distance of 99m.
Solution,
Given that,
- Diameter of the wheel of bicycle = 63cm [ 63m → 0.63m ]
Radius = Diameter / 2
= 0.63 / 2
= 0.315m
- Distance = 99m
- π = 22/7
Therefore, the circumference of wheel of bicycle is,
As we know that,
Circumference of circle = 2πr,
» 2 × ( 22/7 ) × ( 0.315 )
» 2 × 22 × 0.045
» 44 × 0.045
» 1.98cm
The circumference is 1.98cm.
Now, number of revolutions to cover a distance of 99m is,
» 99 / 1.98
» 50
The number of revolves to cover 99m is 50 revolutions.
