Final answer:
To calculate the cost of small and large pizzas at Tony's Pizzeria, the areas of the pizzas must be determined using the formula A = πr^2, and then multiplied by the cost per square centimeter ($8.99). Without the sizes of the pizzas, the precise cost cannot be computed.
Step-by-step explanation:
To determine the cost of a pizza at Tony's Pizzeria based on a given cost per square centimeter, one must first calculate the area of the pizza and then multiply it by the cost per square centimeter. Unfortunately, the information provided doesn't include the sizes of the small and large pizzas, which would be required to perform this calculation. Typically, pizzas are circular, so the area of a pizza can be found using the formula A = πr^2, where A is the area and r is the radius of the pizza. Once the area is established, one would multiply the area by the price per square centimeter, $8.99, to find the total cost.
For example, if the small pizza has a radius of 10 cm, then:
Calculate the area: A = π(10 cm)^2
Multiply the area by the cost per cm2: Area × $8.99/cm2
This process would be repeated for the large pizza using its specific radius. Without the actual measurements, however, the exact costs for the small and large pizzas cannot be given.
