  • Explanation:

    Volume of cylinder =πr2h

    Curved surface area of cylinder = 2πrh

    πr2h/2πrh= 462/264

    r=2×1.75

    r=3.5 m

    πr2h=462

    h = 462/πr2

    =462×7/22×3.5×3.5

    h=12 m

    ∴ Total surface area of the cylinder = 2πr (r+h

    = 2×22/7×3.5(3.5+12)

    =2387/7=341 m2
