at the first we calculate radius=diameter ÷2
=49÷2
r =24.5 cm
now perimeter of the circle =2πr
=2×(22÷7)×24.5
=153.86 cm
Hence 1 revolution traveled distance=153.86 cm
so ,50 revolution traveled distance= 153.86×50=7693 cm

To find the answer we have to follow the steps below:

Given,  

Diameter = 49 cm  

⇒Radius= \frac{49}{2} cm  

Circumference=2× \pi× r  

          = 2×\frac{22}{7}×\frac{49}{2}  

          = 154 cm  

Now, in 50 revolutions distance travelled will be  

          =154× 50 = 7700 cm  

Thus, the bicycle will travel 7700 cm in 50 revolutions if the diameter of the wheel is 49 cm.
