A solid is in the shape of a cone surmounted on a hemi-sphere, the radius of each of them is being 3.5 cm and the total height of solid is 9.5 cm. Find the volume of the solid. 
Height of the cylinder = height of solid – radius of the cone
= 9.5 – 3.5 = 6cm
Volume of the solid = volume of the cone + volume of the cone
= 166.83 cm3
