Question

Example 17 : Find the volume of a sphere of radius 11.2 cm.
Let us tak​

Answer 1

Answer:

The volume of a sphere of radius 11.2 cm is 5884.95cm³

Answer 2

Given :

• Radius of Sphere = 11.2cm

To Find :

• Volume of Sphere .

Solution :

$\longmapsto\tt{Radius=11.2cm}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{\dfrac{4}{3}\times\dfrac{22}{7}\times{11.2}\times{11.2}\times{11.2}}$

$\longmapsto\tt{\cancel\dfrac{123633.6}{21}}$

$\longmapsto\tt\bold{5887.3{cm}^{3}(Approx.)}$

So , The volume of sphere is 5887.3cm³..

_______________________

• Surface Area of Sphere = 4πr²
• Volume of Sphere = 4/3πr³
• Total Surface Area of Hemisphere = 3πr²
• Curved Surface Area of Hemisphere = 2πr²
• Volume of Hemisphere = 2/3πr³
