Answer:
Step-by-step explanation:
volume of cylinder = 6600 cm^3
pi r ^2 h = 6600 cm^3
22/7 x r x r x 21 = 6600 cm^3
66 x r x r = 6600 cm^3
r^2 = 6600/66
= 100
r = 10 cm
csa of cylinder = 2 x pi x r x h
= 2 x 22/7 x 10 x 21
= 1320 cm ^ 2
tsa of cylinder = 2 x pi (r +h)
= 2 x 22/7 x ( 10+21)
= 2 x 22/7 x 31
= 194.85 cm^3
