This math topic focuses on calculating the circumference of a circle using calculators, suitable for introductory lessons on geometry surrounding surface areas of 3D shapes. It includes several problems where students must apply the formula for the circumference of a circle, which is typically \(C = 2\pi r\) or \(C = \pi d\), to find accurate results given different circle illustrations and conditions. This strengthens their skills in practical applications of geometric principles using computational aids.
