  2. Answer:

    curved surface area of a cylinder=(2*pi*r)*h

    area of two bases=(pi*r^2+pi*r^2)=2*pi*r^2

    According to the given data

    4(2*pi*r*h)=2(pi*r^2)

    by solving this

    r=12h/8 {Since given h=12cm)

    r=8cm

    therefore

    curved surface area=2*pi*8*12

    =192*pi
