Question

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.(Use π=22/7)

Answer 1

Step-by-step explanation:

Answer 2

 Total volume  = 166.83 cu.cm.

Step-by-step explanation:

Radius of cone = radius of hemisphere = 3.5cm

Total height = 9.5cm

So height of the cone = 9.5 - 3.5 = 6cm

Volume of cone =  πr²h/3

volume of hemisphere = (2/3)πr³

Total volume = πr²h/3 + (2/3)πr³ =  πr²/3 (h +2r) = 22/7 * 3.5/3 *3.5 (6 + 7)

 = 22/7 * 3.5/3 *3.5 * 13

 = 166.83 cu.cm.
