Question

If a road is of 1000 m and radius of cycle tyre is 10 cm thr how many rotations are possible

Answer 1

Answer:

length of road=1000m

=1000*100=100000cm

radius of cycle tyre =10cm

no. of rotation= 100000/10=10000 revolutions.

Answer 2

Answer:

1592.357 rotations

Explanation:

radius of the tyre (r) = 10cm = 0.1m

circumference of the tyre = 2πr

                                           = 2 x 3.14 x 0.1

                                           = 0.628m

therefore, number of rotations     = 1000m ÷ 0.628m

                                                       = 1592.357
