Circumference (with hint and calculator) (Level 1)

This math topic focuses on calculating the circumference of a circle. It reinforces understanding the relationship between the diameter of the circle and its circumference, applying the formula \( C = \pi d \). Each question provides a different diameter, and students are required to compute the circumference, choosing their answers from multiple options provided. The topic is designed as an introductory part of a broader unit on circle circumferences within geometry. This is enhanced by resources like hints and calculators to aid in learning.
