Question

A solid is in the shape of a right circular cylinder surmounted on a hemisphere of the radius 14 cm. the radius of the cylindrical part is 14 cm and the total height of the solid is 28cm. find the volume of the solid.

Answer 1

is this the answer.....but i think it's wrong so sorry for that but i just tried

Answer 2

Hii friend,

Radius of hemisphere part of the solid = Radius of cylindrical part of the solid = 14 cm.

Total height of the solid = 28 cm

Height of hemispherical part of the solid = It's radius = 14 cm.

Height of cylindrical part of the solid = Total height of the solid - Height of hemispherical part of the solid = 28-14 = 14 cm.

Volume of the solid = Volume of cylindrical part of the solid + Volume of hemispherical part of the solid = πr²h + 2/3πr³ = πr²(h+2/3 r) = 22/7 × 14 × 14 ( 14 + 2/3 × 14) = 44×14(14+28/3)

=> 616(42+28/3)

=> 616(70/3)

=> 616 × 23.33 = 14371.28 cm³.


Hence,


The volume of solid = 14371.28 cm³.


HOPE IT WILL HELP YOU.... :-)
