Answer 2

The answer is option 4.

Explanation:

It is given that the diameter of a wheel is 622 mm so in order to find its radius you have to divide it by 2 :

diameter = 622 mm

radius = 622 ÷ 2

= 311 mm

Next you have to use the formula of circumference of circle, C = 2×π×r where r represents radius :

Let π be 3.14,

Let r be 311 mm,

C = 2×3.14×311

= 1953.08 mm
