Circumference = 3.14 * diameter

Circumference = 3.14 *30

Circumference = 94.2 cm

The circumference of a circle is equal to the diameter multiplied by pi, which is approximately equal to 3.14. Therefore, the circumference of a circle with a diameter of 30 cm would be:

30 cm * 3.14 = 94.2 cm

So the circumference of the circle is approximately 94.2 cm.
