marcel wants to make a mobile using only 3-dimensional solids with curved surfaces. based on this attribute, what figures will marcel use on his mobile

Sounds like it would be a sphere

What are your choices?

To determine which 3-dimensional solids with curved surfaces Marcel can use for his mobile, we need to consider objects that meet this criteria. Here are a few examples of 3-dimensional solids with curved surfaces that Marcel can choose from:

1. Sphere: A sphere is a perfectly symmetrical solid shape with all points on its surface equidistant from its center. It has no edges or faces, only a continuous curved surface. Marcel can use multiple spheres of different sizes to create an interesting mobile.

2. Cylinder: A cylinder is a solid shape with two parallel circular bases connected by a curved surface. Marcel can use multiple cylinders with different heights and diameters to add variety to his mobile.

3. Cone: A cone is a solid shape with a circular base and a curved surface that tapers to a point, known as the apex. Marcel can use multiple cones with different heights and base diameters to incorporate into his mobile.

4. Torus: A torus is a shape resembling a donut or an inner tube. It is a 3-dimensional object with a curved surface created by revolving a circle around an axis in 3D space. Marcel can use torus shapes with varying radii to add unique elements to his mobile.

These are just a few examples of 3-dimensional solids with curved surfaces that Marcel can use for his mobile. He can experiment with different combinations, sizes, and orientations to create a visually appealing and balanced mobile.
