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
=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= cm
Circumference=2× × r
= 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.
