Apply geometric methods to solve design problems

For this picture, I would create a problem related to area of a circle and ratios. The students would be given the diameter of three different sized pizzas then the price of each of those pizza and the students have to determine what deal is the best, that is what has the lowest price per area of pizza ratio. At Domino’s Pizza they have three carry out deals, a Medium for $5.99, and Large for $7.99, and an Extra Large for $9.99. The Medium pizza has a 12 inch diameter, the Large has a 14 inch diameter, and the Extra Large has a 16 inch diameter. This problem relates to the CCSS because it is about using geometric areas and ratios to solve a problem. This picture and problem will get the students interested because I am sure all students like pizza and would love to find the best deal for when they want to buy pizza themselves. Since high school students do not have a lot of money, finding the best deal will definitely draw their attention. The students will work with the concept of ratios and how they can relate to areas.
