Answer:
11 cm x 4 cm rectangular piece of paper is folded and taped without overlapping to make a cylinder of height 4 cm. Find the volume of
Step-by-step explanation:
Height of cylinder=5
circumference of the circle of cylinder=22
2πr=22
πr=11
r=11×7÷22
r=7/2
volume of cylinder =πr^2h
=22/7×7/2×7/2×5
=22×7×7×5/28
=22×7×5/4
=11×7×5/2
=192.5cm^3

Height of cylinder=10
Circumference of the circle of cylinder=22 × 10
2πr=22 × 10
πr= 220 / 2
πr= 110
r=110 × 7/22
r=5 × 7
r= 35
_________________________
Volume of cylinder =πr^2h
=22/7×35×35×5
=22×7×5×5
=22×7×25
=22 × 175
= 3850 cm square.
