Find the capacity in liters of a conical vessel with
radius 7 cm, slant height 25 cm.
Radius of vessel (r)=7cmSlant height of vessel (l)=25cm
Height of vessel (h)=?
As we know that,
l2=h2+r2
⇒h2=(25)2−(7)2
⇒h=√625−49=√576=24cm
Therefore,
Capacity of vessel = Volume of cone
Therefore,
Capacity of vessel =13πr2h
=13×227×72×24
=22×7×8
=1232cm3
=1.232L(∵1000cm3=1L)
