A cylinder perhaps
A 3D shape that can be created using one rectangle and two circles is a cylinder with a rectangular base. The rectangle forms the side of the cylinder, while the two circles can serve as the top and bottom faces. When the rectangle is wrapped around, it connects the edges of the circles, forming a closed cylindrical shape.
A rectangle and two circles.
The shape that would go in the section where two circles overlap is known as a lens shape or a vesica piscis. This area represents the intersection of the two circles, where both circles share common points. The overlapping region can also be described as a curved shape that has two rounded edges, defined by the arcs of the intersecting circles.
There are 2 bases in a cylinder and they are both circles.
Doughnut-shape, or cylinder, depending on how you look at it.
