Answer:
53066 m³
Explanation:
You want the volume of a cone with radius 65 m and height 12 m.
Volume
The formula for the volume of a cone is ...
V = 1/3πr²h
Application
For r = 65 m and h = 12 m, the volume is ...
V = 1/3·3.14·65²·12 = 53066 . . . . cubic meters
The volume of the cone is 53066 cubic meters.
