Question

Nba young boy buys a pizza with a diameter of 7 inches what is the circumference of his pizza

Answer 1

21.98 inches.

Explanation:

Hey there!

If someone were to buy a pizza with a diameter of 7 inches, how would we find the circumference

Well it's really easy!

There is a simple formula needed for these types of question which is:

`C=2\pi r` where C is the circumference, r is the radius, and
`\pi` is pi (3.1415...)

In this problem, we're given the diameter which is two times the radius meaning the radius is 3.5 inches. Now instead of working backwards, we can use a better formula:

`C=\pi dor` where dor means diameter.

In this case, we'll use 3.14 as a substitute for
`\pi`

3.14(7)=21.98

This means that the circumference of the person's pizza is 21.98 inches.
