Question

A vessel is a hollow cylinder fitted with a hemispherical bottom of the same base. The depth of the cylinder is 14/3  m and the diameter of hemisphere is 3.5 m. Calculate the volume and the internal surface area of the solid.

Solution

Given that:

Radius of the same base r=3.5/2=1.75 m

Height of the cylinder h=14/3m

The volume of the vessel is given by

V=pir^2h+2/3pir^3

=3.14xx1.75^2xx14/3+2/3xx3.14xx1.75^3

= 56 m3

The internal surface area of the solid is

S=2pir^2+2pirh

=2xx3.14xx1.75^2+2xx3.14xx1.75xx14/3

= 70.51 m2

Hence, the volume of the vessel and internal surface area of the solid is V = 56 m3, S= 70.51 m2

Is there an error in this question or solution?
