2 pie r h = 4400cm^2
And 2 pie r =220 cm
therefore , (2 pie rh) / (2 pie r)=4400/220
= h = 20cm
since , 2 pie r = 220
2*(22/7)*r = 220
r = 220* ( 7/2*20) = 35cm
Volume = pie r^2 h
=(22/7)*35*35*20
Ans=77000cm^3
hope this was helpful

Circumference = 2x22/7xr = 220 cm^2
=> 44r = 1540
r = 1540/44 = 35 cm
CSA of Cylinder = 2x22/7xrxh = 4400^2
=> 220h = 4400
h = 4400/220 = 20 cm
Volume of Cylinder = 22/7xr^2xh => 22/7x35x35x20 = 440x175 = 77000 cm^3
=> 44r = 1540
r = 1540/44 = 35 cm
CSA of Cylinder = 2x22/7xrxh = 4400^2
=> 220h = 4400
h = 4400/220 = 20 cm
Volume of Cylinder = 22/7xr^2xh => 22/7x35x35x20 = 440x175 = 77000 cm^3
