Question

The wheels on a bike have a 12 inch diameter. What is the circumference? c=Pi,d

Answer 1

Wheels of a bike is a shape of a circle.

Formula to find the circumference of the circle is:

c=πd Where c= circumference and d= diameter of the circle.

Given, diameter: d= 12 inches.

Now plug in d=12 in the above equation to get the circumference c. So,

c=π*12

=3.14*12 Since, π=3.14

=37.68

So, the circumference of the wheel is 37.68.

Answer 2

Hey!

To find circumference, yo multiply
`\pi` by diameter.

`Diameter = 12 \\ \pi = 3.14`

Multiply

`3.14 * 12 = 37.68`

The circumference is 37.68 inches

Hope this helps! :)
