ANSWER


C=22\pi \: m

EXPLANATION

The circumference of a circle is calculated using the formula:


C=2\pi \: r

where r=11 meters is the radius of the circle.

Let us substitute the radius into the formula to obtain,


C=2\pi \: * 11

This simplifies to:


C=22\pi

When we substitute


\pi = 3.14

We get


C=22(3.14) = 69.08m

to the nearest hundredth.
