Answer:
Step-by-step explanation:
So, when a rectangle is folded into a cylinder, the length becomes the circumference of the base/top and the breadth becomes the height. You must visualize this properly for understanding, as these sort of questions will be repeated a lot.
2πr = 88
3.14*r = 44
r = 14.01 cm(approx.)
h = 7 cm
Hence, vol. = πr²h
= 22/7*14.01²*7
= 4318.16 cm³
