Question

Pizza is advertised as containing 250 square inches of pizza. Is 250 the area or the circumference, and how do you know?

a. 250 is the area because square inches represent an area.
b. 250 is the circumference because it's a length measurement.
c. 250 is the volume because it's in cubic inches.
d. 250 is the radius because it's half the diameter.

Answer 1

250 square inches of pizza represents the area because square inches is a unit used to measure area, and in the context of pizzas, it describes how much pizza there is.

Step-by-step explanation:

The question is whether 250 square inches represents the area or the circumference of a pizza. The correct answer is a. 250 is the area because square inches is a unit of measurement for area. When we talk about the size of a pizza, we refer to the area, which tells us how much pizza there is. This is measured in square units, such as square inches, whereas the circumference would be measured in linear units such as inches.

In terms of geometry and dimensional analysis, when we deal with circles, the area is given by the formula A = πr² and the circumference is given by the formula C = 2πr. Here, r represents the radius of the circle. Clearly, the unit for area is in the form of length squared, such as square inches, which matches the description of the pizza's size.
