Answer:
![S=6600\pi \text{ mm}^2](https://tex.z-dn.net/?f=S%3D6600%5Cpi%20%5Ctext%7B%20mm%7D%5E2)
![S\approx 20724 \text{ mm}^2](https://tex.z-dn.net/?f=S%5Capprox%2020724%20%5Ctext%7B%20mm%7D%5E2)
Step-by-step explanation:
A can of fruit is geometrically a cylinder.
We are talking about the <u>surface area of a cylinder</u>:
![S=2\pi rh+2\pi r^2](https://tex.z-dn.net/?f=S%3D2%5Cpi%20rh%2B2%5Cpi%20r%5E2)
![\pi \approx 3.14](https://tex.z-dn.net/?f=%5Cpi%20%5Capprox%203.14)
![r: \text{radius}](https://tex.z-dn.net/?f=r%3A%20%5Ctext%7Bradius%7D)
![h: \text{height}](https://tex.z-dn.net/?f=h%3A%20%5Ctext%7Bheight%7D)
Factoring, we have:
![S=2\pi r (h+r)](https://tex.z-dn.net/?f=S%3D2%5Cpi%20r%09%28h%2Br%29)
Calculating the surface area of the can of fruit:
![S=2\pi (30) (80+30)](https://tex.z-dn.net/?f=S%3D2%5Cpi%20%2830%29%09%2880%2B30%29)
![S=2\pi (30) (110)](https://tex.z-dn.net/?f=S%3D2%5Cpi%20%2830%29%09%28110%29)
![S=6600\pi](https://tex.z-dn.net/?f=S%3D6600%5Cpi)
![S\approx 20724 \text{ mm}^2](https://tex.z-dn.net/?f=S%5Capprox%2020724%20%5Ctext%7B%20mm%7D%5E2)
