The end of a garden hose is enclosed in a mesh sphere of radius 4 cm. If the hose delivers five liters per minute, how much wate

lana [24]

Answer

0.001339 liter

Explanation:

It is given that radius = 4 cm =0.04 m

volume of sphere $V=\frac{4}{3}\pi R^{3}$

$V=\frac{4}{3}\times 3.14\times (4\times 10^{-2})^{3}=2.674\times 10^{-4}$

It is given that hose delivers five liters per minute

So the water flows through sphere per minute is given by 5×2.674× $10^{-4}$ =0.001339 liters
