Answer:
Step-by-step explanation:
Volume of first container = 48 cm³
πr²h = 48 cm³
Second container:
height = (2/3)h
Volume of second container=
![=\pi *r^{2}*(\frac{2}{3}*h)\\\\=\frac{2}{3}*\pi *r^{2}*h\\\\](https://tex.z-dn.net/?f=%3D%5Cpi%20%2Ar%5E%7B2%7D%2A%28%5Cfrac%7B2%7D%7B3%7D%2Ah%29%5C%5C%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D%2A%5Cpi%20%2Ar%5E%7B2%7D%2Ah%5C%5C%5C%5C)
=(2/3)* first container's volume {πr²h = 48 cm³}
![=\frac{2}{3}*48\\\\=2*16\\\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%7D%7B3%7D%2A48%5C%5C%5C%5C%3D2%2A16%5C%5C%5C%5C)
