Height of cylinder = height of paper = 22 cm
CIRCUMSTANCE OF BASE OF CYLINDER = 2πR
10 CM = 2×22/7×R
R = 10×7/44 = 70/44
R = 1.5 CM
Therefore,
VOLUME OF CYLINDER = πR²H
PUT THE VALUE OF R AND H AND SOLVE U WILL GET THE VOLUME OF CYLINDER

Bcz thses answers are lokked by millions + of people
and 10 cm not , 22 cm will be circumference
22 cm = circumference, 10 cm = height of cylinder
Plz correct it, other wise if not me then anyone elso will report it
Are u yet angry ..........., I am only reminding bcz u r a great user
And I have learned many things from u
So, I dont want your answer to be deleyed

☆Hey Mate☆
As its rolled along length wise, so length will become circumference
22cm= 2 × 22/7 × r
22 cm × 7/ 22 × 1/2 = r
3.5 = radius.
Volume = 22/7 × 3.5 cm × 3.5 cm × 10 cm
= 22 × 0.5 cm × 3.5 cm × 10 cm
= 110 × 3.5
= 385 cm^3
Hope it helps☺✌!
