3/5 is smaller then 3/4(you can tell from denominators) 5/8 is smaller then 3/5, and 7/4 is greater then 1, so the only logical one is C. Hope this helped!

Which company’s tower holds the most water?

GuDViN [60]

Answer: First Option

Step-by-step explanation:

The formula to calculate the volume of a cylinder is:

$V = \pi(\frac{d}{2})^2*h$

Where d is the diameter of the cylinder and h is the height.

Notice that the term d is squared. This means that to increase the volume of a cylinder it is more efficient to increase its diameter as well. Therefore, look for the cylinder with the largest diameter among the options.

The first cylinder is 90 ft in diameter and 40 ft in height and its volume is

$V = \pi(\frac{90}{2})^2*40$
