To find the circumference of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference, \( \pi \) (pi) is approximately \( 3.14 \), and \( d \) is the diameter of the circle.
Given that the diameter \( d \) is 22 cm, the calculation would be:
\[
C = 3.14 \times 22
\]
\[
C = 69.08 \, \text{cm}
\]
Thus, the circumference of the circle is **69.08 cm**. The correct answer is A.
