When a right triangle rotates along one of its hypotenuse, what solid shape will it get?

1, the geometric figure formed by the right triangle rotating along its hypotenuse is a broken line gyro (the dotted line is its generatrix). ,

2. Take the distance from the centroid of the surface (parent surface) formed by any polyline or curve to a straight line (including the straight line edge that constitutes the surface) as the radius and take the straight line as the axis. After rotating 360, the volume of the formed rotator is equal to the area of the mother surface multiplied by the distance from the center of mass of the mother surface to the rotation axis and then multiplied by π. Like the former Soviet Union in the 1950s? There is this XX theorem in smirnoff's advanced mathematics course. What's its name? Damn, I forgot. )
