Answer:
Diameter D=5.2 m
Radius (r)=2D=2.6 m
Slant height l=6.8
Height =l2−r2=(6.8)2−(2.6)2=46.24−6.76=39.48m2=6.28m
Volume =31×π×r2=31×722×2.6m×2.6m×6.28m=44.47 m3
Time taken to fill the vessel =(1.8)3m3/min44.47m3=7.62 min

Answer:
Diameter = 5.3 m
Radius = 2.6 m
Slant heights = 6.8
Heights = 12-r2 = 6.8
