Radius of circular region, r = 3cm

Height of Cylinder, H = 40cm

Height of cone, h = 4cm

As we know,

Surface area of hemisphere, AH = 2πr2

Surface area of cylinder, Acy = 2πrH

Surface area of cone is,

ACO = 5πr

Total area = AH + ACY + ACO

On substituting the values, we get,

Total area = πr(2r + 2H + 5)

Total area = π× 3× (6 + 80 + 5)

Total area = 273π

total area of the figure is 273π sq. cm
