To determine the radius of each wheel, we can use the formula for the circumference of a circle:
Circumference = 2πr,
where "Circumference" represents the circumference of the wheel and "r" represents the radius of the wheel.
Given that the circumference of each wheel is 22 inches, we can set up the equation as follows:
22 = 2πr.
To solve for the radius, we'll isolate "r" by dividing both sides of the equation by 2π:
22 / (2π) = r.
Using a calculator for the approximation, we get:
r ≈ 3.5 inches.
Therefore, to the nearest length, the radius of each wheel is approximately 3.5 inches.
