Circumference from Diameter (with calculator) (Level 2)

This math topic focuses on calculating the circumference of a circle given its diameter, leveraging the use of a calculator. This is part of an introductory unit on circle circumferences within a broader Geometry study. Students are provided with multiple-choice questions where each question presents a circle's visual representation (possibly with dimension indicators), and they are to calculate and identify the correct circumference from a list of options. Each problem is designed to build and reinforce the skill set associated with manipulating the formula for circle circumference using diameters.
