The diameter of a circle is given to be 11 mm. It is required to find the circumference.

Recall the formula for the Circumference of a circle with diameter, d:


C=\pi d

Substitute the diameter d=11 mm and the constant π=3.14 into the formula:


C=3.14\cdot11=34.54\text{ mm}

Hence, the circumference of the circle is 34.54 mm.

The answer is 34.54 mm.
