Question

How many litres of water will flow in 7 minutes from a cylindrical pipe 1 cm in diameter, if the water flows at a speed of 30km per hour?

Answer 1

here I have converted 0.5 in 5/10 and multiplying 5/10×5/10 hope u understand plz mark it as brainliest

Answer 2

There is 707.14 liters of water.

Step-by-step explanation:

Since we have given that

Diameter = 1 cm

Radius = 0.5 cm

Water is flowing at 30 km per hour in 7 minutes

Height  =  distance = $speed\times time=30\times \dfrac{5}{18}\times 7\times 60\times 100=900000$

So, volume of water in cylinder would be

$\pi r^2h\\\\=\dfrac{22}{7}\times 0.5\times 0.5\times 900000\\\\=707142.86\ cm^3$

As we know that

$1000\ m^3=1l\\\\1\ cm^3=0.001\ liter\\\\707142.86\ cm^3=707.14\ liters$

Hence, there is 707.14 liters of water.
