charle [14.2K]

Answer:

$\boxed {\tt 69.08 \ centimeters}$

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

$c= \pi d$

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.

$d= 22 \ cm$

$c= \pi* 22 \ cm$

We also know we are using 3.14 for pi. Substitute it in for pi.

$c= 3.14 * 22 \ cm$

Multiply.

$c=69.08 \ cm$

The circumference of the circle is 69.08 centimeters.
