Consider a circle with a radius of 4 units and a square with a side length of 8 units.
Calculate the area of both shapes and determine which has a greater area. The formula for the area of a circle is given by:
$$A =\frac{1}{2} imes ext{radius}^2 \ A_{circle} =\frac{22}{7} imes radius^2$$
and the formula for the area of a square is:
$$A = ext{side} imes ext{side}$$
