The radius of a bicycle wheel is 12 inches. What is the approximate circumference of the wheel?
Answer (2)
Well, the formula for circumference is:
2 π r
We already know that r = 12 , and that π = 3.14 (Approximately), so we have everything we need.
Substitute:
2 π r
= 2 ( 3.14 ) ( 12 )
= ( 24 ) ( 3.14 )
= 75.36
The circumference of the bicycle wheel is approximately 75.36 inches.
Hope this helped!

The approximate circumference of a bicycle wheel with a radius of 12 inches is 75.36 inches, calculated using the formula C = 2 π r . By substituting the given radius into the formula, we find the circumference. This shows the relationship between the radius and the distance around the wheel.
