Answer :

The solid is in the form of a cone surmounted on a hemisphere.


Total height of solid = h = 9.5 m


Radius of Solid = r = 3.5 m


Volume of hemispherical part solid = 2/3 × πr3


= 2/3 × 22/7 × 3.53 m3


= 89.83 m3


Height of conical part of solid = hcone = Total height of solid – Radius of solid


Height of conical part of solid = hcone = 9.5 – 3.5 = 6 m


Volume of conical part of solid = 1/3 × πr2hcone


= 1/3 × 22/7 × 3.52 × 6 m3


= 77 m3


Volume of solid = Volume of hemispherical part solid + Volume of conical part solid


Volume of solid = 89.83 + 77 m3 = 166.83 m3
