Hi I need to get another chance to go back to school subject1
Given:
ratio of altitude height = 2/3
Required:
ratio of volume
Solution:
Assuming that the only difference that the cylinders has is the height, we can solve for the ratio of the volume.
The volume of a cylinder is equal to πr²×height.
ratio of volume = πr²×2/πr²×3
We cancel the pi and the r² since we assume that the cylinders have the same radius.By cancelling, we are left with:
ratio of volume = 2/3
It would be 21 because 7 times 3 equals 21 and the way you get that is 3 drawings per paper
You just have to set the denominator to zero and solve for x
