Idk-

The volume of a cone $V$ can be calculated by the equation $V = \frac{bh}{3}$ where $b$ is the area of the base. If the cone has a radius of $5.5$ then the area of the base is $30.25\pi$ therefore the volume of the cone is $\frac{12 \times 30.25\pi}{3} = 121\pi \approx 380.132711084$ units^3.
