Question

Pam served her apple pie on a 13 inch diameter dish. She wanted to tie a ribbon around the dish to make it a little more festive. How long does the ribbon need to be in order to fit around the dish

Answer 1

40.82 inches

Explanation:

The ribbon length around the dish can also be renamed as the circumference.

We can use this equation to find the circumference: C =
`\pi`d.

This is also circumference is equal to pi multiplied by the diameter.

We can use 3.14 as an estimation for pi.

3.14 x 13 = 40.82

40.82 inches is our circumference/ribbon length.

Answer 2

Hi!

The length around a circle is also known as the circumference.

The formula for circumference of a circle is diameter * pi (
`\pi`)

Therefore,

`13\pi`

For sake of simpleness, we will use 3.14 for pi:

`13(3.14)`

`40.82`

Hence, she needs 40,82 inches of ribbon to properly fit around the dish.
