Question

in how many revolotion can bicycle wheel of diameter 4.9m cover a distance of 46.2km

Answer 1

Answer:Total distance to be travelled = 4.4 km

= 4400 m

Diameter of wheel = 70 cm = 0.7 m

Radius of wheel= 0.7 / 2 m

Circumference of wheel = 2 * pi *r

= 2* 22*0.7 / 7* 2

= 22*0.1

= 2.2 m

No. Of revolutions = Total distance / Circumference of wheel

= 4400 / 2.2

= 2000

Answer 2

Step-by-step explanation:

3.

distance to be covered/perimeter of wheel

peeimeter = Π × diameter

=22× 49/70 =15.4 revolutions

5

perimeter of henispheres attached = Π×56/2= Π×28 = (22×28)/7 = 616÷7= 88

2×240 +(2×88)= 480+ 616
