Circumference from Diameter (with hint and calculator) (Level 2)

This math topic focuses on calculating the circumference of a circle using the formula \( C = \pi d \), where \( d \) represents the diameter of the circle. The problems involve applying this formula to find the circumference given different circle diameters, with hints and calculator use suggested for each problem. The questions challenge students to apply their understanding of geometry concepts related to circles, specifically how to compute a circle’s perimeter using its diameter. These problems are introductory and are meant to develop fundamental skills in working with the geometry of circles.
