Question

Hunter has a choice between 2 pizzas: a circular pizza with a 10-inch diameter, and a square pizza with a 9-inch side. Which statement below is true?

Answer 1

Answer: B. The area of the square pizza is larger.

Step by step solution:

With the information given, we can calculate the area of the circular pizza and the square pizza, to determine which statement is true.

The area of a circle can be calculated using the formula:

`\begin{gathered} A=(\pi)/(4)* D^2 \\ D\text{ = diameter} \end{gathered}`

We know the circular pizza has a 10-inch diameter, replace D on the above formula:

`A=(\pi)/(4)*10^2=25\pi\approx78.54inches^2`

The area of a square can be calculated using the formula:

`\begin{gathered} A=s^2 \\ s=side \end{gathered}`

We know the sides of the square pizza are 9-inches, replace on the above formula:

`A=9^2=81inches^2`
