Question

If you rotate a equilateral triangle by a side, what is the name of the resulting 3d shape

Answer 1

☞ANSWER☜

3D shapes

• Cube Cuboid
• Sphere Square-based pyramid
• Cylinder Triangular prism
• Pentagonal pyramid Hexagonal prism

☞EXPLANATION☜

A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.

Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder
