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)

=3948.40cm^{2} ................(2)

Curved surface area of 2 hemisphere = 2(2πr^{2})

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