Answer:

Step-by-step explanation:

Circumference of its base =110cm

 

2πr = 110

2 ×  22 / 7 × r = 110

44  / 7 × r = 110

r = 17.5 cm

Curved Surface Area = 4400 cm  ²

 

2πrh = 4400

2 ×  22 / 7  × h × 17.5 = 4400

44  / 7 × 17.5 × h = 440

h= 40  / 4400  ×2.5

h = 40 cm

Volume = πr  ² h

=  22  / 7 × 17.5 × 17.5 × 40

= 38500 cm  ²
