Answer: $2025.80ft^2$

Step-by-step explanation:

$Formula: A=2\pi rh+2\pi r^2$

Diameter: 25.4ft

Height: 12.7ft

Radius: $\frac{d}{2}=\frac{25.4ft}{2}=12.7ft$

$A=2(3.14)(12.7ft)(12.7ft)+2(3.14)(12.7ft)^2\\A=1012.90ft^2+1012.90ft^2\\A=2025.80ft^2$

For this case we have to bake an amount of 702 cookies, which were distributed in boxes of 18 for sale. Selling each box at the same price earned a profit of 136.50 dollars, you want to know the unit cost of each box of cookies.

Let $"x"$ be the number of boxes of cookies:

So, to know the number of boxes we divide 702 cookies among 18:

$x = \frac {702} {18}\\x = 39$

So, we have Tyler sold 39 boxes of cookies

Now, let $"y"$ be the cost of each box of cookies, to know the unit cost or sale price of the cookie boxes, we divided 136.50 dollars among 39 boxes of cookies, then:
