The diameter of a wheel is 63 cm . What is the distance covered by the wheel by making 100 revolutions? [Use $$\pi = \frac{22}{7}$$​]

Correct option is B

Given:

Diameter of wheel = 63cm

Number of revolutions = 100

Formula Used:

Circumference of a circle =$$2\pi r$$​​

Solution:

Radius of wheel =$$\frac{63}{2}$$​ cm

Total distance = n $$\times$$​ Circumference of wheel

​$$= 100 \times 2 \times \frac{22}{7} \times \frac{63}{2}$$​​

= 19800cm

= 198m
