Answer:
The volume of the cone is 42.6 m^3
Step-by-step explanation:
The volume of a cone is given by the area of the base multiplied by the height of the cone and divided by three. The base is a circle, so it's area is computed by the following:
Abase = pi(r^2) = 3.14(2.2^2) = 15.2 m^2
We can then compute the volume of the cone that is:
Vcone = Abase*h/3 = 15.2*8.4/3 = 42.56 m^3
The volume of the cone is 42.6 m^3
