Finding The Coefficient Of Pi

A simple walkthrough of the circumference formula C = 2πr applied to a circle with radius 2, showing step by step how the numbers combine to give 4π. The animation highlights that the coefficient of π is simply the number multiplying it, helping students quickly identify it as 4. Useful for ASVAB test-takers reviewing basic geometry formulas and circle measurements.
