Answer:
4601 cubic meters
Explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)*π*r^2*h.
If the diameter is 26 m, then the radius is half that, or 13.
Then the volume here is
V = (π / 3)(3.14159)(13 m)^2*(26 m)
= π*4601.39 m^3
Rounding this off to the nearest cubic meter, we get 4601 cubic meters.
