Question: 1 / 400

If a circle has a circumference of 10cm, what is the diameter?

5 cm

A circle's diameter is the length of a straight line passing through the center of the circle and connecting two points on the circle's edge. The formula for diameter is "Circumference divided by Pi," or d = c / 3.14. Since the circumference is 10cm, the diameter can be found by dividing 10 by 3.14, giving us approximately 5 cm. The other options are incorrect because they do not follow the formula for finding the diameter and are either too large or too small. Option B, 10cm, is equal to the circumference and therefore cannot be the diameter. Option C, 20cm, is double the circumference and option D, 25cm, is 2.5 times the circumference. Therefore, A is the correct choice.
