Question

If the shape in the diagram rotates about the dashed line, which three-dimensional object will be formed?

Answer 1

It is a three-dimensional figure that remembers a cone, but the sides are not a right line but curved (concave) and the bottom is not plane but a convexed surface. This shape will wooble but not fall. I hope this explanation helps you because you didn't place the answer choices.

Answer 2

Cone

Explanation:

Rotation means the circular moment of an object about some axis or center.

In the given figure, the shape is rotated along the dashed line.

The size of the object remains same after rotation.

After rotating about the dashed line, we observe that the object formed is three- dimensional and is in the shape of a cone.
