Question

an overhead cylinder tank has diameter 7cm and hight 4m .find the volume of tank in liter​

Answer 1

$\huge\fcolorbox{red}{cyan}{15.4\:l}$

Step-by-step explanation:

• Radius => d/2 = 3.5 cm

• Height => 4 m = 400 cm

$\bf{ \boxed{volume = \pi \: {r}^{2} \: h}} \\ = > \bf{lets \: put \: the \: values} \\ = > \frac{22}{7} \times 3.5 \times 3.5 \times 400 \\ = > 22 \times 0.5 \times 3.5 \times 400 \\ = > 15400 \: {cm}^{3}$

Now Lets Convert it in litres :-

$1000 \: {cm}^{3} = 1 \: l \\ = > 15400 \: {cm}^{3} = \frac{15400}{1000} l \\ = > \boxed{15.4 \: l}$

Hope it helped
