$V=\frac{1}{2}r^{2}\theta h$
The base represents the sector of a circle. The area of a sector of a circle is $A=\frac{1}{2}r^{2}\theta$ where $r$ is the radius of the sector of the circle and $\theta$ is the central angle in radians. Since the base represents the sector of a circle, the area of the base is also equal to $A=\frac{1}{2}r^{2}\theta$. Multiplying this area by the height to find the volume $V$, $V=A\times h$ $V=\frac{1}{2}r^{2}\theta\times h$ $V=\frac{1}{2}r^{2}\theta h$
