I think the volume would be 33.51
Well, the formula for circumference is:
![2πr](https://tex.z-dn.net/?f=2%CF%80r)
We already know that
![r=12](https://tex.z-dn.net/?f=r%3D12)
, and that
![π=3.14](https://tex.z-dn.net/?f=%CF%80%3D3.14)
(Approximately), so we have everything we need.
Substitute:
![2πr](https://tex.z-dn.net/?f=2%CF%80r)
![=2(3.14)(12)](https://tex.z-dn.net/?f=%3D2%283.14%29%2812%29)
![=(24)(3.14)](https://tex.z-dn.net/?f=%3D%2824%29%283.14%29)
![=75.36](https://tex.z-dn.net/?f=%3D75.36)
The circumference of the bicycle wheel is approximately 75.36 inches.
Hope this helped!

Answer:
314.2in^2
Step-by-step explanation:
GIven data
diameter= 10in
radius= 5in
Height= 2in
The expression for the curved surface area (CSA) of a cylinder is given as
CSA=2πrh
CSA=2*3.142*5*2
CSA=62.84 in^2
The material needed to make one pipe is 62.84in^2
Hence the material need for 5 pipes is
=62.84*5
=314.2in^2
Answer:
6%
Step-by-step explanation:
0.3 x 0.2 = 0.06
0.06 x 100 = 6
