Answer 2

Answer:

$\Large{\boxed{\red{\underline{17600 \: cm \: or \: 176 \: m}}}}$

Formula used:

Volume of Cylinder = $\pi {r}^{2} h$

Step-by-step explanation:

Given,

Height of cylinder = 14 cm (length of rectangle rolled)

Radius = 20 cm

Volume of Cylinder = $\pi {r}^{2} h$

$\boxed{Take\: the\: value \:of\: pi\: (π) \:as\: = \: \frac{22}{7}}$

= $\frac{22}{7} \times {20}^{2} \times 14$

= $22 \times {20}^{2} \times 2$

= $44 \times {20}^{2}$

= 44 × 400

= 17600 cm

1 m = 100 cm

So, $\frac{17600}{100}$

= 176m

Therefore, volume of cylinder is $\large{\boxed{\red{\underline{17600 \: cm \: or \: 176 \: m}}}}$
