Answer 1

Answer :

Option 2)

Explanation :

Given the base radius = 8 cm

Height = 20 cm

$\bigstar \boxed{ \red{ \sf \: Volume \: of \: Cylinder = Area \: of \: base \times height}}$

In order to calculate the Volume we have to Find the Area of Base First.

We know that A cylinder has two circular plane ends. Two plane ends are parallel and are known as bases of the Cylinder.

$\bigstar \boxed{ \red{ \sf \: Area \: of \: Circle =\pi {r}^{2} }}$

$\longrightarrow \sf \: \dfrac{22}{7} \times 8 \times 8$

$\longrightarrow \sf \: \cancel\dfrac{1408}{7}$

$\longrightarrow \sf \: 201.14285...(Approx)$

Let's Put the Value Now :

$\bigstar \boxed{ \red{ \sf \: Volume \: of \: Cylinder = Area \: of \: base \times height}}$

$\longrightarrow \sf \: 201.14285 \times 20$

$\longrightarrow \sf \: 4022.85 7$

If we round off the value then answer obtained is 4.0218 litre.

Answer 2

$\huge{\underline{\underline{\mathfrak{\red{AnswEr :-}}}}}$

$\longrightarrow$ Option (B) 4.0218 is correct

$\large{\underline{\sf{Step- to-step explanation}}}}}$

Given that, the radius base is 8 cm and height is 20 cm

Volume of cylinder $\longrightarrow$ πr²h

$\longrightarrow$$\frac{22}{7} \times {8}^{2} \times 20$

$\longrightarrow$ 4.02285

$\longrightarrow$After Round off the answer will be $\longrightarrow$4.0128 Litre..
