Answer:
36
Step-by-step explanation:
The circumference of the circle in terms of pi, based on the area of the circle is 6 π.
<h3>How to find the circumference?</h3>
The area of a circle can be found by the formula:
= π x radius x radius
= π x radius ²
If the area of the circle is 9π cm², then the radius is:
= √9π cm²
= 3 π cm
The diameter of a circle is double the radius so the diameter is:
= 3 x 2
= 6 cm
The circumference of a circle is:
= π x diameter
= π x 6
= 6π
