A circle has a diameter of 22 cm. What is its circumference?
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.
