Calculate the circumference of this circle drawn inside a square with sides of length 6.8cm.

Sure, here are the steps to calculate the circumference of the circle:

1. Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square. So, the diameter of the circle is 6.8 cm.

2. The formula to calculate the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

3. Substituting the given diameter into the formula, we get C = π * 6.8 cm.

4. Using the approximation of π as 3.14, the circumference C = 3.14 * 6.8 cm = 21.352 cm.

So, the circumference of the circle is approximately 21.352 cm.
