Curved surface area/Total surface area = 2πr (r + h)/2rh

=>1/3=2πr (r + h)/2πrh
=>r=2h (after calculating)

Total surface area is 1848cm^2
=>2πr (r + h) = 1848cm^2 
=>2π x 2h x(2h+h) = 1848cm^2 (r=2h)
=>h^2=49
=>h=7 (after calculating)

if h=7cm than r = 2x7=14cm

Volume of cylinder = πr^2h=(22/7) x (14)^2 x 7 = 4312cm^3
