Answer:
Length of paper=.circumference of
cylinder
22=2πr
r=22/2π = 22x7/2x22=3.5 cm
h=25cm
vol of cylinder = πr 2h
=22/7. x3.5^2 x 25=962.5cm3

Answer:
Step-by-step explanation:
In the cylinder formed,
Height = 25cm
Circumfrence = 2πr = 22 cm
2×22/7×r = 22
r = 22×7/2×22
r = 7/2 cm
Volume = πr^2h
22/7 ×7/2 ×7/2 × 25
962.5
