Question

A vessel is in the form of hollow hemisphere mounted by a hollow cylinder the diameter of hemisphere is 14 cm and the total height of The vessel is 13 cm find the inner surface area of vessel

Answer 1

inner surface area of vessel= surface area of cylinder+surface area of hemisphere
=
$2\pi \times r \times h + 2\pi \times {r}^{2}$
height of cylinder = total height of vessel - 7cm (radius of hemisphere)= 6cm
$264 {cm }^{2} + 308 {cm}^{2} = 572 {cm}^{2}$

Answer 2

Answer:

Step-by-step explanation:

inner surface area of vessel= surface area of cylinder+surface area of hemisphere

=

2\pi \times r \times h + 2\pi \times {r}^{2}

height of cylinder = total height of vessel - 7cm (radius of hemisphere)= 6cm

264 {cm }^{2} + 308 {cm}^{2} = 572 {cm}^{2}
