Answer:

Explanation:

The key is to find out the entire volume the tank can hold when it is full, then take 2/3 of that amount. The volume of a cylinder is


V=\pi r^2h and filling in:


V=3.14(3)^2(3) (if the diameter is 6 m, the radius is 3) so

V = 84.78 m³ when it is full all the way. If we need the amount that makes up 2/3 of that:


(2)/(3)(84.78)=56.52m^3
