Webradius = 14/2 = 7 units Since the pizza is of circular shape, we can use the formula for the area of a circle to calculate the area of the pizza. Area of the circle = πr 2 Substituting the pi (π) value and radius in the formula, we get, Area = 22/7 × 7 × 7 = 22 × 7 = 154 square units. Therefore, the area of the pizza = 154 square units.
