Question

Tire rim has a diameter of 15 in. What is the circumference of the tire rim? Use 3.14 for Pi.

23.55 in.
46.10 in.
47.1 in.
94.2 in.

Answer 1

The correct option is C. 47.10 inches

Explanation:

Diameter of the tire rim is given to be 15 inches

So, The radius of the tire rim will be 7.5 inches

Now, we need to find the circumference of the tire rim

And, The circumference of the tire rim is given by the formula :

Circumference = 2·π × radius

⇒ Circumference of the tire rim = 2 × 3.14 × 7.5

⇒ Circumference of the tire rim = 47.1 inches

Therefore, The correct option is C. 47.10 inches
