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
