Question

How much should mary charge the customer to the nearest cent? use 3.14 for pie

Answer 1

step 1

Find out the area of the closet

The area is equal to the area of a right triangle plus the area of a semicircle

so

`A=(1)/(2)(7)(6)+(1)/(2)^{}\cdot3.14\cdot((7)/(2))^2`
`\begin{gathered} A=21+19.2325 \\ A=40.2325\text{ ft2} \end{gathered}`

step 2

Find out the total charge

40.2325*5.60+150=$375.30

therefore

the answer is $375.30
