Answer 2

Given :

• Diameter of Base of Cylinder = 14cm.
• Height of Cylinder = 40cm.

To Find :

• Volume of Cylinder.

Solution :

$\longmapsto\tt{Diameter=14cm}$

$\longmapsto\tt{Radius=\cancel\dfrac{14}{2}=7cm}$

$\longmapsto\tt{Height=40cm}$

Using Formula :

$\longmapsto\tt\boxed{Volume\:of\:Cylinder=\pi{{r}^{2}h}}$

Putting Values :

$\longmapsto\tt{\dfrac{22}{\not{7}}\times{7}\times{\not{7}}\times{40}}$

$\longmapsto\tt{22\times{7}\times{40}}$

$\longmapsto\tt\bold{6160{cm}^{3}}$

So , The volume of Cylinder is 6160cm³..

• C.S.A of Cylinder = 2πrh
• T.S.A of Cylinder = 2πr(r+h)
• Volume of Cylinder = πr²h
