If you rotate a equilateral triangle by a side, what is the name of the resulting 3d shape
Katyanochek1 [597]
<h2> ☞ANSWER☜</h2>

<h3>3D shapes</h3>
  • Cube Cuboid
  • Sphere Square-based pyramid
  • Cylinder Triangular prism
  • Pentagonal pyramid Hexagonal prism

<h2> ☞EXPLANATION☜</h2>

<em><u>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.</u></em>

<em><u>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</u></em>
