Answer:
50% change in volume
Step-by-step explanation:
<h2>
This problem bothers on the mensuration of solid shapes.</h2>
In this problem we are to find the volume of the first cylinder and compare with the second cylinder.
Given data
Volume v = ?
Diameter d=
?
Radius r = ![10 in](https://tex.z-dn.net/?f=10%20in)
Height h= ![5 in](https://tex.z-dn.net/?f=5%20in)
we know that the volume of a cylinder is expressed as
![volume = \pi r^{2}h](https://tex.z-dn.net/?f=volume%20%3D%20%5Cpi%20r%5E%7B2%7Dh)
Substituting our given data we have
![volume = \pi*10^{2}*5\\ volume= \pi *100*5\\volume= 500\pi in^{3} \\](https://tex.z-dn.net/?f=volume%20%3D%20%5Cpi%2A10%5E%7B2%7D%2A5%5C%5C%20volume%3D%20%5Cpi%20%2A100%2A5%5C%5Cvolume%3D%20500%5Cpi%20in%5E%7B3%7D%20%5C%5C)
The first cylinder as a volume of ![500\pi](https://tex.z-dn.net/?f=500%5Cpi)
The change in volume is ![750\pi - 500\pi = 250\pi](https://tex.z-dn.net/?f=750%5Cpi%20-%20500%5Cpi%20%3D%20250%5Cpi)
percentage = ![\frac{250\pi }{500\pi } *100](https://tex.z-dn.net/?f=%5Cfrac%7B250%5Cpi%20%7D%7B500%5Cpi%20%7D%20%2A100)
![percentage=](https://tex.z-dn.net/?f=percentage%3D)
