Answer 2

Answer:

$\sf \: \green{volume \: of \: cylinder \: is \: 123.2 cm³}$

Step-by-step explanation:

$\large \: { \sf \: We \: Have ,}$

$\sf \: Radius \: of \: base \: of \: cylinder = 1.4 \: cm$

$\sf \: Height \: of \: cylinder = 2 dm = 20 cm \: \green{(1d m = 10 cm)}$

$\large{ \sf \: We \: know \: that - }$

$\boxed {\green{ \underline{\sf \: Volume \: of \: cylinder \: = πr²h}}}$

$\implies \frac{22}{7} \times 1.4 \times 1.4 \times 20$

$\huge \boxed{\implies \: \sf123.2 \: cm^{2} }$

$\sf \: Hence, \: volume \: of \: cylinder \: is \: 123.2 cm³$
