Answer:
The area of the label is ![12\pi\ cm^{2}](https://tex.z-dn.net/?f=12%5Cpi%5C%20cm%5E%7B2%7D)
Step-by-step explanation:
step 1
Find the radius
we know that
The volume of the cylinder (can of tuna) is equal to
![V=\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20h)
In this problem we have
![V=18\pi\ cm^{3}](https://tex.z-dn.net/?f=V%3D18%5Cpi%5C%20cm%5E%7B3%7D)
![h=2\ cm](https://tex.z-dn.net/?f=h%3D2%5C%20cm)
substitute and solve for r
![18\pi=\pi r^{2} (2)](https://tex.z-dn.net/?f=18%5Cpi%3D%5Cpi%20r%5E%7B2%7D%20%282%29)
Simplify
![18=r^{2}(2)](https://tex.z-dn.net/?f=18%3Dr%5E%7B2%7D%282%29)
![r^{2}=9](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D9)
![r=3\ cm](https://tex.z-dn.net/?f=r%3D3%5C%20cm)
step 2
<em>Find the lateral area of the can</em>
The lateral area of the cylinder (can of tuna) is equal to
![LA=2\pi rh](https://tex.z-dn.net/?f=LA%3D2%5Cpi%20rh)
we have
![r=3\ cm](https://tex.z-dn.net/?f=r%3D3%5C%20cm)
![h=2\ cm](https://tex.z-dn.net/?f=h%3D2%5C%20cm)
![LA=2\pi (3)(2)=12\pi\ cm^{2}](https://tex.z-dn.net/?f=LA%3D2%5Cpi%20%283%29%282%29%3D12%5Cpi%5C%20cm%5E%7B2%7D)
Answer:
yes Wyatt is very correct
x = 4
8 multiplied by itself is 64.
And so, 2 times itself is 4.
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
