The formula for the circumference of a circle is:
C = πd
where C is the circumference, d is the diameter, and π is approximately 3.14
In this problem, we are given the value of the circumference as 126.5 cm, so we can set up an equation and solve for the diameter:
126.5 = 3.14d
Dividing both sides by 3.14, we get:
d = 126.5/3.14
Simplifying this expression, we get:
d ≈ 40.3
Therefore, the diameter of the bicycle tire is approximately 40.3 cm when rounded to the nearest tenth.
