oohai here is Ur ans:-
given d=5.2
=>r=d/2=5.2/2=2.6
r=2.6
=>slant h=6.8m
=>l^2=r^2+h^2
=>6.8^2=2.6^2 +h^2
=>46.24=6.76+h^2
=>h^2= 46.24 -6.76
=>h^2=39.48
=>h=√39.48
=>h=6.28m
=>v= 1/3 πr^2h
= 1/3 ×22/7×2.6×2.6×6.8
=>1/3 ×22/7 ×42.45
=>1/3 ×22×6.064
=>44.4
time taken to fill the vessel =44.4m^3/1.8m^3
=>24.6 (approximately)
if my ans is helpful 2 u....mark as brainlist .....
