Question

if a rectangle was rotated about the y - axis, like the one shown below. what would be the resulting three - dimensional shape? cone cylinder pyramid sphere

Explanation:

When a rectangle is rotated about an axis, the resulting 3 - D shape has circular bases and straight parallel sides. A cylinder has two circular bases and a curved surface connecting them, which is formed when a rectangle rotates about an axis. A cone is formed by rotating a right - triangle, a pyramid has triangular faces meeting at a vertex, and a sphere is formed by rotating a semi - circle.

Answer:

Cylinder
