Explanation:
The volume of the right circular cone can be calculated as follows:
volume =
We are given that:
diameter = 6.1 ft.......> This means that: radius (r) = 6.1 / 2 = 3.05 ft
height (h) = 17.5 ft
Substitute with the givens in the above equation to get the volume as follows:
volume =
volume = 170.477 which is approximately 170.5 ft³
Hope this helps :)
