Answer:
82896 ![mm^{2}](https://tex.z-dn.net/?f=mm%5E%7B2%7D)
Step-by-step explanation:
Use the formula for the surface area of a cylinder, which is ![A=2\pi rh+2\pi r^{2}](https://tex.z-dn.net/?f=A%3D2%5Cpi%20rh%2B2%5Cpi%20r%5E%7B2%7D)
Plug in the the numbers for each variable given. Your substituted formula should now look like this: ![A=2(3.14) (60)(160)+2(3.14)(60)^2](https://tex.z-dn.net/?f=A%3D2%283.14%29%20%2860%29%28160%29%2B2%283.14%29%2860%29%5E2)
Solve for A
Answer:
144
Step-by-step explanation:
exponents first: ![4^{3} = 64](https://tex.z-dn.net/?f=4%5E%7B3%7D%20%20%3D%2064)
then division: 100/5 = 20
now we have: 20 x 4 + 64
then multiply: 20 x 4 = 80
then add: 80 + 64 = 144
