    Answer:

    Volume of cylinder πr

    2

    h

    Now, if r=

    2

    r

    &h=h2

    New CSA =2πrh

    =2π(

    2

    r

    )×(h×2)

    =2πrh

    It will remain same

    Step-by-step explanation:

    In a cylinder, radius is doubled and height is halved, then curved surface area will be

    (a) halved

    (b) doubled

    (c) same

    (d) four times

    volume and surface area
