(1)- Given,
radius of a cone, r =7cm,and
Slant height, l =25cm
Let the height of the cone be =h cm
Since,we know that
Height (h) of cone 
Now,
Capacity of a vessel=volume of cone
Volume of cone
Therefore, capacity of the conical vessel
= 
= 1.232 litres
(2)Given,
Height,h= 12cm,and
Slant height, l =13cm
Let,radius of cone = r cm
Since we know that
Radius (r) of cone 
Volume of cone
Therefore, capacity of the conical vessel
= 
= 
litres

1. L^2 = h^2 + r^2 L = slant height h= height r= radius
25^2 = h^2 + 7^2
h^2 = 625 - 49 = 576
after taking square root
h = 24
volume of cone = L^2 = h^2 + r^2
= 1/3 * 3.14 *7^2 * 24
=3692.64/3
volume of cone =1230 cm^3
1L = 1000cm^3
therefore answer is 1.230 L
