Question

find the volume of sphere whose radius is o.63m​

Answer 1

Answer:

Given:-

Radius of a sphere =0.63m

To find:-

Volume of the sphere

Solution:-

r=0.63m

We know that in a sphere

$\boxed{\sf Volume=\dfrac {4}{3}\pi r^3}$

• substitute the values

$\qquad\quad\displaystyle\sf {:}\longrightarrow \dfrac {4}{3}\times \dfrac {22}{\cancel {7}}\times (\cancel {0.63})^3$

$\qquad\quad\displaystyle\sf {:}\longrightarrow \dfrac {4\times 22}{\cancel {3}}\times\cancel { (0.9)}^3$

$\qquad\quad\displaystyle\sf {:}\longrightarrow 88\times (0.3)^3$

$\qquad\quad\displaystyle\sf {:}\longrightarrow 88\times 0.027$

$\qquad\quad\displaystyle\sf {:}\longrightarrow 2.376 m^3$

$\therefore$ Volume of the sphere is 2.376 m $^3$
