The wheel on a bicycle has a circumference of 56.52 inches. What is the radius of the tire?
18 inches
7.5 inches
6 inches
9 inches
To find the radius of the tire, we can use the formula for the circumference of a circle:
C = 2πr
where C is the circumference and r is the radius.
Given that the circumference of the tire is 56.52 inches, we can substitute this value into the formula:
56.52 = 2πr
To solve for r, we need to divide both sides of the equation by 2π:
r = 56.52 / (2π)
Using a calculator to evaluate this expression:
r ≈ 9 inches
Therefore, the radius of the tire is approximately 9 inches.
