Question

Elainas old bicycle had tires with a 12-inch diameter her new bicycle had tires with a 16-inch diameter what is the difference in the circumference of the tires use 3.14 for pie

Answer 1

The difference between the circumference of the tires is 12.56 inches.

Explanation:

Given:

Diameter of old bicycle tires = 12 inch

Diameter of new bicycle tires = 16 inch

We need to find the difference in circumference of the tires.

Solution:

First we will find the circumference of Old bicycle tires.

Circumference can be calculated by π times diameter.

Circumference of Old bicycle tire =
`\pi * 12 = 37.68\ in`

Now we will find the circumference of new bicycle tire.

Circumference of New bicycle tire =
`\pi * 16 = 50.24\ in`

Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;

framing in equation form we get;

difference between the circumference of the tires =
`50.24-37.68 =12.56\ in`

Hence The difference between the circumference of the tires is 12.56 inches.
