G.t csa= 1760,
csa=2pi*r*h
2pi*r*h=1760
2*22/7*rh=1760
rh=1760*7/44
rh=280.....(1).
Also given that volume v= 12320
pi*r^2*h=12320
22/7*r*rh=12320
22/7*r*280=12320
r*6160/7=12320
r=12320*7/6160
r=14
sub. The value of 'r'
csa=1760
2pi*r*h=1760
2*22*14/7*h=1760
2*22*2*=1760
88*h=1760
h=1760/88
h=20
csa=2pi*r*h
2pi*r*h=1760
2*22/7*rh=1760
