Your question :- a rectangular piece of paper is 22 cm long and 12 cm wide. A cylinder is formed by rolling the paper along its length. Find the volume of ythe cylinder.
Answer:-
LENGTH OF PAPER = CIRCUMFERENCE OF BASE OF CYLINDER.
2πr = 22
=> r = 22 *7/2*22
=> r =7/2
volume of cylinder = πr2h
=22/7*7/2*7/2*12
=462 cm3.
