Question

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

Answer 1

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:

V = 616cm³

Step-by-step explanation:

V = πr²h. diameter= r + r= 7+ 7=14

= 22/7 × (7)²×4

=22/7 × 49 × 4

= 22×7×4

= 616 cm³
