circumfrence = 2πr
2πr = 110
2 × 22/7 × r = 110
r = 110 × 7 / 22 × 2
r = 770 / 44
r = 17.5
CSA = 2πrh
2 × 22 / 7 × 17.5 × h = 4400
110 × h = 4400
h = 4400 / 110
h = 40
volume = πr^2h
22/7 × (17.5)² × 40
22/7 × 306.25 × 40
22 × 43.75 × 40
38500cm^3

2πrh = 4400
rh = 4400/2 × 7/22
rh = 700
2πr = 110
r = 110/2 × 7/22
r = 35/2 cm
h = 700 × 2/35
h = 40 cm
V = πr^2h
= 22/7 × 35/2 × 35/2 × 40
= 38500 cm^3
