Answer 1

Answer:

25 minutes

Step-by-step explanation:

Given,Diameter of conical vessel = 5.2 m.

Then, radius of conical vessel = 2.6 m.

We know that slant height (l) = √h² + r²

6.8² =  (2.6)² + h²

46.24 - 6.76 = h²

39.48 = h²

h = 6.28 m

We know that volume = (1/3) * πr²h

⇒ (1/3) * (22/7) * (2.6)² * 6.28

⇒ 44.47 m³

Given that rate of water pouring is 1.8 m³ per minute.

Time taken to fill the vessel:

⇒ 44.47/1.8

⇒ 24.7 minutes

⇒ 25 minutes.

Hope this helps!
