here circumference will be 11cm height is 4 cm
volume is pi r2 h
pi r2= 11 h= 4
hence volume is 11×4= 44cm3
circumference is 11 because one side is height then other will form circular ending
u can try it practically
this may help u

Area of rectangle = Curved surface area of cylinder = 11 X 4 cm=44cm
Now , CSA of Cylinder = 2πRH
44cm=2πR(4)cm
R = 7/4cm
Volume of Cylinder = πR^2H
=(22/7)(7×7/4×4)4cm^3
=77/2 cm^3
Hope it work"s.
