Given : paper 24 cm * 22 cm
Make cylinder by folding each side
To Find : Which one has more Curved surface area , volume
Solution:
paper 24 cm * 22 cm
24 cm is height and 22 cm is circumference of base
2πr = 22
h = 24 cm
Curved surface area =2πrh = 22 * 24 cm²
2πr = 22
=> 2(22/7)r = 22
=> r = 7/2
Volume = πr²h
= (22/7)(7/2)²24
= 924 cm³
paper 24 cm * 22 cm
22 cm is height and 24 cm is circumference of base
2πr = 24
h = 22 cm
Curved surface area =2πrh = 24 * 22 cm²
Curved surface area of both is same
2πr = 24
=> 2(22/7)r = 24
=> r = 42/11
Volume = πr²h
= (22/7)(42/11)²22
= 1008 cm³
1008 > 924
Volume of this case is higher
