Question

what solid is generated when the right triangle is rotated about the line? triangular pyramid triangular prism cylinder cone

Explanation:

When a right - triangle is rotated about one of its legs (the line in this case), the resulting solid has a circular base (formed by the rotation of the other leg) and a pointed top (the vertex of the right - angle). A cone is defined as a solid with a circular base and a single vertex. A triangular pyramid has a triangular base. A triangular prism has two triangular bases and three rectangular faces. A cylinder has two circular bases.
