Answer:
d
Step-by-step explanation:
The answer is 39 because volume equals length times width times hieght
Answer:
![r=\sqrt{\dfrac{3V}{\pi h}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%5Cdfrac%7B3V%7D%7B%5Cpi%20h%7D%7D)
Step-by-step explanation:
The volume of a cylinder is given by :
.....(1)
Where
r and h are the radius and the height of the cylinder.
We need to solve the equation of r. Cross multiplying both sides in equation (1).
![3V=\pi r^2h](https://tex.z-dn.net/?f=3V%3D%5Cpi%20r%5E2h)
Dividing both sides by
. So,
![\dfrac{3V}{\pi h}=\dfrac{\pi r^2h}{\pi h}\\\\r^2=\dfrac{3V}{\pi h}\\\\or\\\\r=\sqrt{\dfrac{3V}{\pi h}}](https://tex.z-dn.net/?f=%5Cdfrac%7B3V%7D%7B%5Cpi%20h%7D%3D%5Cdfrac%7B%5Cpi%20r%5E2h%7D%7B%5Cpi%20h%7D%5C%5C%5C%5Cr%5E2%3D%5Cdfrac%7B3V%7D%7B%5Cpi%20h%7D%5C%5C%5C%5Cor%5C%5C%5C%5Cr%3D%5Csqrt%7B%5Cdfrac%7B3V%7D%7B%5Cpi%20h%7D%7D)
So, the radius of the cylinder is equal to

8th, I wanna graduate already
It would be .3 of the lessons assuming that they add up to 1 at the end
