CSA = 2*pi*r*h
264 = 2*22/7*r*h
r*h = (264*7)/(22*2)
r*h = 42
h = 42/r
Volume of the cylinder = πr²h
924 = 22/7*r²*42/r
r = (924*7)/(22*42)
r = 7 m
h = 42/7
h = 6 m

Answer:
csa of cylinder=2πrh
2πrh=264
πrh=264/2
=132
volume of cylinder=924
πr^2h=924
r*132=924
r=924/132
=7m
πrh=132
22/7*7*h=132
h=6m
