We have,
Ratio between radius and height of a cylinder = 2:3
r/h = 2/3
h = 3/2 r
Volume of cylinder = 1617 cm3
πr2h = 1617
22/7 × r2 × 3/2r = 1617
r3 = 1617×7×2 / 22×3
= 343
r = 3√343
= 7cm
Radius = 7 cm
Height = 3/2r = 3/2 × 7 = 21/2 = 10.5cm
∴ Total surface area of cylinder = 2πr (h+r)
= 2 × 22/7 × 7 (10.5+7)
= 770 cm2
