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
