Which is a better deal - a 10-inch round pizza or a 9-inch square pizza?
Assuming the same price, equal thickness and 10 is the diameter, calculate the areas of a circle vs. a square (9*9) and decide.
10 INCH ROUND PIZZA
To determine which is a better deal between a 10-inch round pizza and a 9-inch square pizza, we need to compare the sizes and calculate the area of each pizza.
To determine the area of a round pizza, we use the formula for the area of a circle: A = πr², where A represents the area and r represents the radius. In this case, the radius is half the diameter, so the radius of the 10-inch pizza is 10/2 = 5 inches. Substituting the radius into the formula gives us A = 3.14 x (5)² = 3.14 x 25 = 78.5 square inches.
To determine the area of a square pizza, we use the formula for the area of a square: A = s², where A represents the area and s represents the side length. For the 9-inch square pizza, the side length is 9 inches. Substituting the side length into the formula gives us A = 9 x 9 = 81 square inches.
Comparing the areas, we see that the 9-inch square pizza has an area of 81 square inches, while the 10-inch round pizza has an area of 78.5 square inches. Therefore, the 9-inch square pizza is a better deal in terms of the amount of pizza you get for your money.
