Question

a milk tank is in the form of cylinder whose radius is 1.5 m and length is 7m find the quality of milk in L that can be stored i n the tank​

Answer 1

$\huge{ \bold{ \underline{ \green{ \sf{DETAILED \: ANSWER}}}}}$

Given

Radius = 1.5m = $\frac{15}{10} m$

Height = 7m

Step by step explanation

Therefore, Volume of the tank = πr²h

= $\frac{22}{7} \times ( \frac{15}{10} ) {}^{2} \times 7m ^{3}$

= $\frac{22 }{7} \times \frac{15}{10} \times \frac{15}{10} \times 7m ^{3}$

= $(11 \times 3 \times 3) \div 2m ^{3}$

= $\frac{99}{2} m ^{3}$

= 49.5 m³

Since, 1 m³ = 1000 litres

Therefore, quantity of milk in the tank = 49.5 × 1000 litres

= $\frac{495}{10} \times 1000 \: litres$

= 49500 litres

Conclusion

The quantity of milk that can be stored in the tank is 49500 litres.
