Answer:
115500 cm³, 115.5 litres
Step-by-step explanation:
c.s.a of a cylinder is 2πrh
2πrh = 6600
πrh = 3300 ----1
circumference of base of a cylinder is 2πr
2πr = 220
πr = 110 -----2
from eq. 1 and 2,
πrh/πr = 3300/110
h= 30
r = 3300/ πh
r= 35
volume of a cylinder = πr²h
22/7 × 35² × 30
= 22 × 5 × 35 × 30
=115500 cm³
