Question

A bycycle's wheel covers a distance of 2 m in 1 revolution. How much distance will cover in 600 revolution? Write your answer in km.

Answer 1

Answer:

I have gave you a correct answer so please mark me as brainlist.

Step-by-step explanation:

Diameter of circular wheel =2r=56cm

Circumference =2πr=π(2r)=56πcm

1 revolution of wheel covers distance equal to its circumference =56πcm

Total distance covered by wheel =1.1km=1.1∗1000m=1100m=1100∗100cm=110000cm

Total Distance = Number of revolutions ∗ 1 revolution distance

Number of revolutions =

1revolutiondistance

TotalDistance

=

56π

110000

=625.25≈625

The number of revolutions made by a bicycle wheel 56 cm in diameter in covering a distance of 1.1 km is 625.
