V = (1/3) x pi x radius^2 x h
= 1/3pir^2 x h
The only way other than directly memorising it is to learn how to derive it
The formula for area is derived from using integration to continuosly sum the areas of circles as their radii approach 0 (a point) over a distance (h)
Volume of a sphere is found similarly, but continuosly summing areas of small flat cylinders.

The volume of a cone is 1/3r^2(pi)(h). The formula is of a cone is the same as 1/3 of the volume of a cylinder.

Volume of a cone is 1/3 of the volume of a cylinder with the same radius and height.
Just like volume of pyramid is 1/3 of the volume of a prism with the same base (cross section) and height (length).
Good Luck

Volume of a cone (radius R, vertical height H, slant height L)
V = pi*R^2*H/3
V = pi*(L^2 -- H^2)*H/3
V = pi*R^2*{sqrt(L^2 -- R^2)}/3
once you visualize the figure marked with R, L, H you will never forget, also remember R^2 + H^2 = L^2

radius = r
height = h
V = (1/3) π r ² h
Easy way to remember?????
Repetition I suppose.
