Tiny is ordering a pizza and cant decide between a round pizza with a diameter of 4 inches or a rectangular pizza that is 12 inches by 14 inches. The round pizza is 9.50 and the rectangular pizza is 10.00.

Which is larger?
How much larger is it?
Which pizza is the better buy according to the price per inch?
Suzie doesn't like crust on the pizza. Which pizza hes the least crust?

I am not a teacher, but want to be one, and you don't have to believe my answer. I am a student that really loves math and it comes easy to me.

rectangular pizza is larger by 155.44 in.
rectangular is the better buy

If each pizza has one inch of crust on the edges.
rectangular pizza crust- 25 in.
circular pizza crust- 9.42 in.
considering the size of the pizzas the rectangular one would have less. More than half of the circular pizza would be crust.

rectangular pizza area- 168 in.
circular pizza area- 12.56 in.

To determine which pizza is larger, you need to compare their areas. The area of a round pizza can be found using the formula A = πr^2, where r is the radius (half of the diameter). The area of a rectangular pizza is found by multiplying its length and width (A = l x w).

For the round pizza with a diameter of 4 inches, the radius is 4/2 = 2 inches. So, the area is A = π(2^2) = 4π square inches.

For the rectangular pizza that measures 12 inches by 14 inches, the area is A = 12 x 14 = 168 square inches.

Comparing the two areas, you can see that the rectangular pizza is larger with an area of 168 square inches, compared to the round pizza with an area of 4π (approximately 12.57) square inches.

To determine how much larger the rectangular pizza is, you can subtract the area of the round pizza from the area of the rectangular pizza. 168 - 12.57 ≈ 155.43 square inches. Therefore, the rectangular pizza is approximately 155.43 square inches larger.

To find out which pizza is the better buy according to the price per inch, you need to divide the price by the area (in square inches) of each pizza.

For the round pizza: Price per square inch = 9.50 / 12.57 ≈ 0.756 dollars per square inch.

For the rectangular pizza: Price per square inch = 10.00 / 168 ≈ 0.0595 dollars per square inch.

Comparing the two prices per square inch, you can see that the rectangular pizza has a lower price per square inch, making it the better buy in terms of price.

If Suzie doesn't like crust on the pizza, she might prefer the round pizza since it has a smaller crust area compared to the rectangular pizza. The round pizza has a crust circumference of 2πr (2π x 2 = 4π inches), while the rectangular pizza has no crust areas since it is rectangular in shape.
