Given radius of hemispherical ends = 7cm

Height of body (h+2r)= 104cm  

Curved surface area of cylinder = 2πrh

Substitute ‘h’ value in (1)

Curved surface area of cylinder =  2π(7)(90)

=3948.40cm2    ................(2)

Curved surface area of 2 hemisphere = 2(2πr2)

Total curved surface area = (2) + (3)
