Given:
Required
The information that shows by SSS
By SSS implies that, the three sides of both triangles are congruent
Already, we have:
The third side of is
The third side of is
So, for both to be congruent by SSS, the third sides must be congruent
i.e.
In Cartesian coordinates, the region (call it ) is the set
In the plane , we have
which is a circle with radius . Then we can better describe the solid by
so that the volume is
While doable, it's easier to compute the volume in cylindrical coordinates.
Then we can describe in cylindrical coordinates by
so that the volume is
