Answer 1

To create a three-dimensional object like an orange, you would need to rotate a specific shape around an axis.

Among the given options:

- **Right triangle**: Rotating a right triangle around one of its sides will create a three-dimensional object, but it will not resemble an orange.

- **Square**: Rotating a square around an axis through its center will create a three-dimensional object, specifically a cube, not an orange.

- **Hemisphere**: Rotating a hemisphere around its flat circular edge will create a sphere, which is similar in shape to an orange.

- **Rectangle**: Rotating a rectangle around one of its longer sides will create a cylinder, not a spherical object like an orange.

The correct choice is **Option #3: hemisphere**, as it can be rotated to create a sphere, which closely resembles an orange.
