Pavan built a conical flask which required 550m2 of canvas. If the radius of flask is 7m, then how much water he can fill into the flask(in litres).
Since, the area of canvas= 550 m2 = πrl
⇒ l = 25 m
⇒ h = (l2−r2)12
Volume of conical flask = 13 πr2 h = 1232m3
We know that 1m3 = 1000 l
So, volume in litres = 1232000 l
