Question

Find the distance covered by the wheel of a truck in 100 rotations if the diameter of the wheel is 49 cm

Answer 1

Diameter of circle is = 49 cm

Circumference= 2πr = 49 × π = 49π cm

We know, in one cycle the wheel covers a distance equal to its circumstances.

Therefore,in 100 rvolutions the wheel covers a distance equal to = 49π × 100 = 49×3.14×100 = 15386 cm (ans)

Answer 2

Step-by-step explanation:

Diameter of circle is = 49 cm

Circumference= 2πr = 49 × π = 49π cm

We know, in one cycle the wheel covers a distance equal to its circumstances.

Therefore,in 100 rvolutions the wheel covers a distance equal to = 49π × 100 = 49×3.14×100 = 15386 cm (ans)
