Find the circumference if the diameter is 5.4 cm.

The circumference is the length of the closed curve. The length of the circle can be found using the formula:

L = п * D, where L is the circumference, п is a mathematical constant (п = 3.14), D is the diameter of the circle. In our case, we get:

L = 3.14 * 5.4;

L = 16.956.

Answer: L = 16.956 cm.
