Given:

The diameter of the wheel is 2 feet.

Number of revolution = 100

To find:

The total distance covered by the bicycle.

Solution:

The circumference of a circle is:

$C=2\pi r$

Where, r is the radius of the circle.

The diameter of the wheel is 2 feet. So, the radius of the circle is 1 feet.

Putting
$\pi =3.14, r=1$ in the above formula, we get

C=2(3.14)(1)

C=6.28

It means the distance covered by the wheel in one revolution is 6.28 feet.

Number of revolution is 100. So, the total distance covered by the wheel in 100 revolution is:

6.28* 100=628

The total distance covered by the bicycle in 100 revolution is 628 feet.

Therefore, the correct option is B.
