Question

find the c. s. a. of cylinder whose radius is 3cm and height 14cm​

Answer 1

Given :

• Radius of Cylinder is 3 cm .
• Height of Cylinder is 14 cm .

To Find :

• Curved Surface Area of Cylinder .

Solution :

$\longmapsto\tt{Radius=3\:cm}$

$\longmapsto\tt{Height=14\:cm}$

Using Formula :

$\longmapsto\tt\boxed{C.S.A\:of\:Cylinder=2\pi{rh}}$

Putting Values :

$\longmapsto\tt{2\times\dfrac{22}{{\cancel{7}}}\times{3}\times{{\cancel{14}}}}$

$\longmapsto\tt{44\times{3}\times{2}}$

$\longmapsto\tt{44\times{6}}$

$\longmapsto\tt\bf{264\:{cm}^{2}}$

So , Curved Surface Area of Cylinder is 264 cm² ..

_______________________

• Curved Surface Area of Cylinder = 2πrh
• Total Surface Area of Cylinder = 2πr(r+h)
• Volume of Cylinder = πr²h
