This math topic focuses on practicing how to find the circumference of a circle given its radius. It enables students to apply the formula for the circumference of a circle, which is typically \( C = 2\pi r \), where \( C \) is the circumference and \( r \) is the radius. Learners are presented with various circles, each accompanied by multiple-choice answers that represent different equations for the circumference. This includes correctly applying the formula as well as avoiding common misconceptions or calculation errors.
