Question

How do you find the circumference of a circle with a diameter of 3 inches?

Answer 1

`3pi` inches or about `9.42` inches(rounded to nearest hundredth's place)

Explanation:

The formula for the circumference of a circle is `2pir` where `r` is the radius, or `pid` where `d` is the diameter.

In this problem, we are given the diameter, so we can use the `pid` formula to find the circumference. Plug in `3` for the diameter:
`pi(3) = 3pi` inches

If you want to simplify this even further, we know that `pi ~~ 3.14`, so `3(3.14) = 9.42` inches(rounded to nearest hundredth's place)

Hope this helps!
