1. 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

2πr = 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.
