If two cylinders are similar and the ratio between the altitude lengths is 2:3, what is the ratio of their volumes
hram777 [196]
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

What does this add up to -8g^2+(2g^2-4h)
bixtya [17]
Hi there!
The question here is -8g² + (2g² - 4h), and we are asked to find the sum of it. First, we can remove the parentheses by distributing the 'invisible' 1 next to the addition sign. This gives us -8g² + 2g² - 4h. Next, we can simplify the expression by finding like terms, which would be -8g² and 2g², as they both have the same variable to the same exponent. Therefore, our answer would be -6g² - 4h. Hope this helped and have a phenomenal day!
