Question

a rectangle is rotated, using one of its longer sides as the axis of revolution. what three - dimensional object is generated by this rotation? 3 of 4 questio rectangular prism cylinder cube cone

Explanation:

When a rectangle is rotated about one of its longer sides (axis of revolution), the shorter side of the rectangle traces out a circular path. The resulting 3 - D object has two circular bases (from the rotation of the two endpoints of the shorter side) and a curved lateral surface (from the rotation of the shorter side itself). A rectangular prism and a cube are formed by translating (not rotating) 2 - D shapes. A cone is formed by rotating a right - triangle.

Answer:

B. Cylinder
