CSA OF CYLINDER = 2πRH
1320 = 2×22/7×21×H
H = 1320×7/44×21
H = 9240/924 = 10cm
VOLUME OF CYLINDER = πR²H
= 22/7×21×21×10
= 13860cm³

CSA of cylinder = 2*22/7*r*h
1320 = 2*22/7*21/2*h
h = 1320*7*2/2*22*21
h = 18480/924
h = 20 cm
Vol. of cylinder = 22/7*r^2*h
= 22/7*21/2*21/2*20
= 6930 cm^3
1320 = 2*22/7*21/2*h
h = 1320*7*2/2*22*21
h = 18480/924
h = 20 cm
Vol. of cylinder = 22/7*r^2*h
= 22/7*21/2*21/2*20
= 6930 cm^3
