Question

How do you find the circumference of a circle with diameter 7.2cm?

Answer 1

`7.2 pi` cm

Explanation:

The formula for the circumference of a circle is:

`Circumference = 2 xx pi xx Radius`
or
`Circumference = pi xx Diameter`

You're given the diameter, so we can use the second formula.
`Circumference = 7.2 pi` cm

Your class might use different approximations for `pi`, such as `3.14` or `22/7`. Make sure to use them if you have to.
