Question

(2)Find the volume of the right circular cylinder which has the base radius of 21 m and height 14 m .

Answer 1

Answer:

V≈19396.19m³________________

Answer 2

Given :

Radius of Cylinder is 21 m .

Height of Cylinder is 14 m .

To Find :

Volume of Cylinder .

Solution :

$\longmapsto\tt{Radius=21\:m}$

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

Using Formula :

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

Putting Values :

$\longmapsto\tt{\dfrac{22}{{\cancel{7}}}\times{21}\times{21}\times{{\cancel{14}}}}$

$\longmapsto\tt{22\times{21}\times{21}\times{2}}$

$\longmapsto\tt\bf{19404\:{cm}^{3}}$

So , The Volume of Cylinder is 19404 cm³ .

____________________

Curved Surface Area of Cylinder = 2πrh

Total Surface Area of Cylinder = 2πr(r+h)

Volume of Cylinder = πr²h

Here :

r = radius

h = height

π = 3.14 or 22/7
