Part A: How many square inches of pizza is the pizza from Tallahassee? Show every step of your work

To find the area of a circle, we use the formula A = πr^2, where A is the area and r is the radius of the circle.

Given that the diameter of the pizza from Tallahassee is 16 inches, we can find the radius by dividing the diameter by 2:
radius = 16 inches / 2 = 8 inches

Now we can plug the radius into the formula to find the area:
A = π(8 inches)^2
A = π(64 square inches)
A = 64π square inches

Therefore, the pizza from Tallahassee has an area of 64π square inches.

Next, we can calculate the approximate area by using the value of π as approximately 3.14159:
A ≈ 64 * 3.14159
A ≈ 201.06176 square inches

So, the pizza from Tallahassee has approximately 201.06 square inches of pizza.
