Answer:

Circumference of its base =110cm

2πr=110

2 \times  \frac{22}{7}  \times r = 110

 \frac{44}{7}  \times r = 110

r=17.5cm

Curved Surface Area =4400cm²

2πrh=4400

⟹2 \times  \frac{22}{7}  \times h \times 17.5 = 4400

⟹\frac{44}{7}  \times h \times 17.5 = 4400

⟹h =  \frac{4400}{40}  \times 2.5

so, h=40cm

Volume = πr²h

 \frac{22}{7}  \times 17.5 \times 17.5 \times 40

  = 38500 {cm}^{2}
