This math topic focuses on calculating the circumference of a circle given various diameters. Students apply the formula for circumference \( C = \pi \times d \), engaging with the relationship between diameter and circumference using the constant \( \pi \). Problem sets include multiple-choice questions where students select the correct expression for the circumference based on provided diameters. This helps reinforce the understanding of the fundamental properties of circles within the context of introductory geometry.
