L.P.G and Ball

Answer 2

Heya !


Here is yr answer.........


Sphere:
~~~~~~~

<> It haves only 1 face.. it is curved

<> SA of sphere = 4π²


Hemisphere:
~~~~~~~~~~~

<> It haves 2 faces

<> 1 is curved

<> CSA of hemisphere = 2πr²


Cylinder:
~~~~~~~~

<> It haves 3 faces

<> 1 is curved...

<> CSA of cylinder = 2πrh

Cone :
~~~~~~

<> It haves 2 faces

<> 1 is curved

<> CSA of cone = πrl


Cube :
~~~~~~


<> It haves 6 faces

<> In 6 faces , 4 are curved..

<> CSA of cube = 4a²


Cuboid:
~~~~~~~

<> It also haves 6 faces

<> In 6 faces, 4 are curved...

<> CSA of Cuboid = 2h(l+b)



Hope it hlpz....
