Calculating the Area of a Circle

The video tutorial discusses how to determine which pizza is preferable when hungry by comparing their areas. It explains that the larger pizza provides more food due to its greater area. The tutorial demonstrates how to calculate the area of both a small and a large pizza using the formula for the area of a circle, pi times radius squared. The small pizza has a radius of 8 cm, resulting in an area of 200.96 square centimeters, while the large pizza has a radius of 14 cm, resulting in an area of 615.44 square centimeters. The larger pizza is shown to be a better choice for a hungry group as it offers over three times more area.
