Answer 1

Correct Question :-

Find the Volume of a Hemisphere with Radius 7cm.

AnswEr:-

$\sf\implies\;718.66 \;cm$

______________________________________

Step by Step Explanation:-

We know that,

Volume of Hemisphere = $\sf\large\frac{2}{3}πr^3$

And, Radius is given 7cm.

Now,

$\implies\sf\large\frac{2}{3} \times\; \frac{23}{7} \times \;(7)^3$

$\sf\implies \; 718.66 \; cm$

So, Volume of Hemisphere is $\sf \;718.66 \; cm.$

Answer 2

Answer:

$\large\boxed{\sf{718.67\;\;{cm}^{3}}}$

Step-by-step explanation:

There is given a hemisphere.

Radius , r = 7 cm

We have to find the volume.

We know that volume of hemisphere is :

$\large \boxed{ \red{v = \frac{2}{3} \pi {r}^{3} }}$

So, according to this formula, we get :

$= > v = \frac{2}{3} \times \frac{22}{7} \times {7}^{3} \\ \\ = > v = \frac{44}{3} \times {7}^{2} \\ \\ = > v = \frac{44 \times 49}{3} \\ \\ = > \bold{ \sf{ v = 718.67 \: {cm}^{3} }}$
