Question

A hollow hemisphere has inner radius of 5 cm and thickness 1 cm find the volume of the hollow hemisphere:
please answer this question correctly how give this answer correctly I will make him or her as a brainlest.
plz.... ​

Answer 1

Given:-

• Inner Radius of hollow hemisphere is 5 cm.
• Thickness of hollow hemisphere is 1 cm.

To find:-

• Volume of hemisphere.

Solution:-

We know that,

$\boxed{ \sf \bold{Volume \: of \: hemisphere = \cfrac{2}{3} \pi {r}^{3} }}$

In which,

• r is Radius of hemisphere.

Radius = 5 + 1 = 6 cm.

Put, Radius in Volume formula :

$\implies \sf \cfrac{2}{3} \times \dfrac{22}{7} \times 6 \times 6 \times 6$

$\implies \sf \cfrac{9504}{21}$

$\implies \sf 452.571$

Therefore,

Volume of hemisphere is 452.571 $\sf cm^{3}$.
