Question

find the volume of the cylinder whose radious is 0.7 and height is 1.4​

Answer 1

Answer:

$\huge \: 2.156 \: {unit}^{3}$

Step-by-step explanation:

$radius \: of \: cylinder = 0.7 \: unit \\ \\ height \: of \: cylinder = 1.4 \: unit \\ \\ = > formula \: of \: volume \: of \: cylinder \: \huge \: \pi {r}^{2} h \\ \\ = > value \: put \: in \: formula \\ \\ = > \huge \: \pi {r}^{2} h \\ \\ = > \frac{22}{7} \times 0.7 \times \times 0.7 \times 1.4 \\ \\ = > \frac{22}{7} \times \frac{7}{10} \times \frac{7}{10} \times \frac{14}{10} \\ \\ = > \frac{22 \times 7 \times 14}{10 \times 10 \times 10} \\ \\ = > \frac{2156}{1000} \\ \\ = > 2.156 \: {unit}^{3}$
