Find the Circumference of a Circle Using the Radius

The video tutorial explains how to calculate the circumference of a circle with a radius of 10 inches. It begins by defining the radius and then introduces the formula for circumference: 2 multiplied by pi multiplied by the radius. The tutorial substitutes the values of pi as 3.14 and the radius as 10 inches into the formula. It then demonstrates how to manually calculate the circumference without a calculator, resulting in a final measurement of 62.8 inches. The video concludes by emphasizing the importance of using the correct units for linear measurements.
