Question

The diameter of a wheel is 1.26 m. The distance traveled in 500 revolutions is ____________.

Options

• 2670 m

• 2880 m

• 1980 m

• 1596 m

Answer 1

The diameter of a wheel is 1.26 m. The distance traveled in 500 revolutions is 1980 m.

Explanation:

Radius of the wheel `= 1.26/2 = 0.63  "m"`

Distance traveled in one revolution

`= 2 pi "r" = 2 xx 22/7 xx 0.63`

= 3.96 m

`therefore` Distance travelled in 500 revolutions

= 500 x 3.96

= 1980 m.
