Question

The diameter of a wheel is 28 cm, if the wheel rotates 8 times, then how far it will travel?​

Answer 1

Diameter (d) = 28 cm

Radius (r) = d/2

r = 28/2

r = 14 cm

Perimeter = 2πr

Perimeter of the wheel = 2×22/7×14

= 88 cm

Distance covered = 88×8

= 704 cm

The distance covered by a wheel of diameter 28cm if rotated 8 times will be 704 cm.
