Question

Find the volume of cylinder whose Diameter is 14 cm and height is 4 cm​

Answer 1

Step-by-step explanation:

Answer:

The volume of cylinder is 616 cm³.

Step-by-step explanation:

Solution :

We're given with :

Diameter = 14 cm

Height = 4 cm

Radius :

$\sf{\longrightarrow{\dfrac{Diameter}{2}}}$

$\sf{\longrightarrow{\dfrac{14}{2}}}$

$\sf{\longrightarrow{7\:cm}}$

$\rule{300}{1.5}$

The volume of the cylinder =

$\boxed{\sf{Volume \: of \: the \: cylinder =\pi{r}^{2}h}}$

$\sf{\longrightarrow} \: \pi \times ( {7})^{2} \times 4$

$\sf{\longrightarrow} \: \dfrac{22}{7} \times 49 \times 4$

$\sf{\longrightarrow} \:22 \times 7 \times4$

$\sf{\longrightarrow} \:154 \times 4$

$\sf{\longrightarrow} \: 616 \: {cm}^{3}$

Therefore, the volume of cylinder is 616 cm³.

Answer 2

Answer:

176 cm ^3

Given, height 14cm and diameter =4cm

Volume of a Cylinder of Radius "R" and height "h" =πR 2 h

Radius of the base = 4/2

=2cm

Hence, volume of the given cylinder =

7/22 ×2×2×14=176cm ^3
