Find the capacity in litres of a conical vessel with

(i) Radius 7 cm, slant height 25 cm


(ii) Height 12 cm, slant height 13 cm

(i) Radius (r) = 7 cm

Slant height (l) = 25 cm


Height (h) =


= 24 cm


Volume = r2h


= * * 7 * 7 * 24


= 154 * 8


= 1232 cm3


Capacity of conical vessel = () litres


= 1.232 litres


(ii) Height (h) = 12 cm


Slant height (l) = 13 cm


Radius (r) =


= 5 cm


Volume = r2h


= * * 5 * 5 * 12


= cm3


Capacity of conical vessel = () litres


= litres
