X equals 10
There you go:)
im pretty sure you got it right with 40!!
Answer:
Possible dimensions are
and ![h=16\,\,cm\,,\,r=2\,\,cm](https://tex.z-dn.net/?f=h%3D16%5C%2C%5C%2Ccm%5C%2C%2C%5C%2Cr%3D2%5C%2C%5C%2Ccm)
Step-by-step explanation:
Given:
Volume of a cylinder is ![64\pi\,\,cm^3](https://tex.z-dn.net/?f=64%5Cpi%5C%2C%5C%2Ccm%5E3)
To find: Dimensions of a cylinder
Solution:
Let
denote height of a cylinder.
Volume of a cylinder = ![\pi r^2h](https://tex.z-dn.net/?f=%5Cpi%20r%5E2h)
Therefore,
![64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h](https://tex.z-dn.net/?f=64%5Cpi%3D%5Cpi%20r%5E2h%5C%5C64%3Dr%5E2h%5C%5C4%5E2%5C%2C4%3Dr%5E2h)
One possible dimension can be
.
Also,
can be written as ![16(2^2)=hr^2](https://tex.z-dn.net/?f=16%282%5E2%29%3Dhr%5E2)
So, another possible dimension can be ![h=16\,\,cm\,,\,r=2\,\,cm](https://tex.z-dn.net/?f=h%3D16%5C%2C%5C%2Ccm%5C%2C%2C%5C%2Cr%3D2%5C%2C%5C%2Ccm)
