Step-by-step explanation:
l=33 cm
w=32 cm
length of the sheet= circumference of the circle
circumference of the circle=2 x pi x r
2 x (22/7) x r=33 cm
r=(33 x 7)/(2 x 22)
r=5.25 cm
capacity (or) volume of the cylinder=pi x r^2 x h
=(22/7) x (5.25)^2 x 32
=2772 cm^3
Hence, capacity (or) volume of the cylinder=2772 cm^3

Answer:
2772 cm^3
Step-by-step explanation:
length=l=33 cm
wide = w= 32 cm
Length of sheet = circumference of circle
circumference of circle= 2 pie r
33 cm = 2*22\7*r
r = 33*7\2*22 = 5.25 cm
volume of cylinder = 22/7*5.25*5.25*32 = 2772 cm^3
