Question

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

Answer 1

Answer:

Circumference ≅ 195 mm

Step-by-step explanation:

The circumference of a circle is equal to: $2*\pi *radius$

Since $Diameter = 2*radius$ we can replace that in the circumference equation giving us:

$Circumference = \pi *Diameter$

We know Diameter = 622 mm and pi = 3.14 so:

$Circumference = \pi *Diameter = 3.14 * 622 mm = 195.308 mm$
