| Recall that the circumference can be found by the formula:
C = 2 × ∏ × r,
where ∏ is a constant equal to 3.14;
r is the radius of the circle.
The diameter of the circle is equal to two radii. Means:
C = ∏ × D,
where D is the diameter of the circle.
From the condition of the problem D = 10 cm.Then:
C = 3.14 x 10 = 31.4 cm.
Answer: The circumference is 31.4 cm.
