Question

Volume with PI math problem. We are looking at number one. It says a pumpkin pie cost $12.55 at Bobby’s bakery. If the pie has a Diameter Of 12 inches, what is the cost per square inch of the pie.

Answer 1

the area is

`A=2*\pi* r^2`

the radius is 6in because is the half of diameter

now find the area

`\begin{gathered} A=2*3.14*6^2 \\ A=226.08 \end{gathered}`

then divide the cost between the area

`(12.55)/(226.08)=0.055`

the cost per square inch of the pie is $0.055
