Answer:

1232 m^3 to nearest whole number.

Explanation:

The volume of a cone = 1/3 π r^2 h where r = radius of base and h = height.

The radius of the base = 1/2 * 14 = 7m.

The height can be found by using the Pythagoras theorem:

25^2 = h^2 + 7^2

h^2 = 625 - 49 = 576

h = √576 = 24m

So the volume = 1/3 π * 7^2 * 24

= 1231.504 m^3.
