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
Its either A or B but my bets are on A
2/3x + 6 = 1/2x + 1/4x ...multiply everything by 12
8x + 72 = 6x + 3x
8x + 72 = 9x
72 = 9x - 8x
72 = x
Answer is D.
28:44 is the ratio but you have to simplify it. Divide both by 4. 28 divided by 4 = 7; 44 divided by 4 = 11
1/4
The coefficient is the number attached to a variable.
