$7.2 π$ $7.2 pi$ cm

Explanation:

The formula for the circumference of a circle is:

$C i r c u m f e r e n c e = 2 \times π \times R a d i u s$ $Circumference = 2 xx pi xx Radius$
or
$C i r c u m f e r e n c e = π \times D i a m e t e r$ $Circumference = pi xx Diameter$

You're given the diameter, so we can use the second formula.
$C i r c u m f e r e n c e = 7.2 π$ $Circumference = 7.2 pi$ cm

Your class might use different approximations for $π$ $pi$ , such as $3.14$ $3.14$ or $\frac{22}{7}$ $22/7$ . Make sure to use them if you have to.
