Question

What is the volume of the sphere? Around you answer to the nearest whole number.

Answer 1

Step-by-step explanation:

Diameter=10cm

Radius=Diameter/2=10/2=5cm

Now

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

$\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{4}{3}\times \dfrac{22}{7}\times 5^3$

$\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{88}{21}\times 125$

$\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{11000}{21}$

$\\ \tt{:}\leadsto Volume_{(Sphere)}=523.8$

$\\ \tt{:}\leadsto Volume_{(Sphere)}=524units^3(Approx)$
