Question

Find the distance covered by a wheel of diameter 70cm in 130 revolutions

Answer 1

Step-by-step explanation:

in one rev , distance covered = 2πr = 2π(35) = 70π cm

therefore, in 130 rev , distance covered = 70π(130) = 910π cm

Answer 2

Step-by-step explanation:

Diameter of wheel=70cm

2r=70cm

r=35cm

Distance traveled in one revolution=2πr

=2*22/7*35

=220cm

Total revolution=130

Total distance traveled=Total no. of revolution*distance covered in 1 revolution

=130*220

=28600cm

=286m
