Question

If the diameter of a small pizza is 8 inches what is the area in square inches

Answer 1

Given the information, we have the following circle shaped pizza:

we can use the following equation for the area of a circle:

`A=\pi\cdot r^2`

in this case, since the diameter is d = 8in, the radius is:

`\begin{gathered} r=(d)/(2)=(8)/(2)=4 \\ \Rightarrow r=4 \end{gathered}`

then, using the formula, we get:

`\begin{gathered} A=\pi\cdot(4)^2=(3.1416)(16)=50.2656 \\ \Rightarrow A=50.3in^2 \end{gathered}`

therefore, the area of the small pizza is 50.3 square inches
