Final answer:

Option A. The circumference of the wheels of a car with a radius of 11 inches is approximately 22 inches.

Step-by-step explanation:

The question asks for the circumference of a car wheel with a given radius. To find the circumference of a circle, we use the formula C = 2πr, where C is the circumference and r is the radius of the circle. In this case, the radius is given as 11 inches. Substituting the given radius into the formula, we get C = 2 × π × 11 inches = 22 π inches. Since π is approximately 3.14, then 22 π is approximately 22 × 3.14, which equals 69.08 inches. The answer closest to this value is 66 inches (Option D).

The circumference of a circle is calculated using the formula:

Circumference = 2 × π × radius

Given that the radius of the wheels of the car is 11 inches, we can substitute this value into the formula:

Circumference = 2 × π × 11 inches

Calculating the value gives us:

Circumference ≈ 22 inches

Therefore, the circumference of the wheels of the car is approximately 22 inches.
