Pavan built a conical flask using 550 m2 of aluminium sheet. If the radius of the flask is 7m, then how much water can he fill into the flask?
1232 m3
1232000 l
Since, the area of aluminium sheet = Curved surface area of flask
⇒550 m2=πrl
⇒550=227×7×l
⇒l=25 m
From the relation l2=h2+r2
h=√(l2−r2)
⇒h=√252−72
⇒h=24 m
Volume of conical flask = 13 πr2h
=13×227×72×24
=1232 m3
