This question is Based on Mensuration Chapter of M.L Aggarwal book for ICSE BOARD for class 10.
This figure is of a rectangular tin foil with its given size and it is wrapped around to form a cylinder with given height. So, find the volume of the cylinder.
This is the Question Number 04, Exercise 17.1 of M.L Aggarwal.
Given height of the cylinder, h = 16 cm
When rectangular foil of length 22 cm is folded to form cylinder, the base circumference of the cylinder is 22cm
2Ï€r = 22
r = 22×7/22×2
= 3.5 cm
Volume of the cylinder, V = πr2h
= (22/7)×3.52×16
= 616 cm3
Hence the volume of the cylinder is 616 cm3.
