This math topic focuses on calculating the circumference of a circle given its diameter. It encourages practicing the formula for circumference, \(C = \pi \times \text{diameter}\), using an approximate value for π (a bit more than 3), which simplifies the calculation without a calculator. It covers basic to intermediate problems, teaching students to accurately apply the formula and understand the relationship between diameter and circumference. The outlined problems show varying levels of difficulty and multiple-choice answers to encourage self-assessment and reinforcement of the concept.
