1.	the radius of a whe of a road roller is 56cm.if he wheel rotates 150turns ,then find the distance covered by it
Answer» 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 Total Distance = 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.

Answer»

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

Total Distance

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.
