A road bike has a wheel diameter of 622 mm. What is the circumference of the wheel? Use 3.14 for Pi.

1.) 976.24 mm

2.) 976.54 mm

3.) 1,852.08 mm

4.) 1,953.08 mm

The answer is option 4.

Step-by-step 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
