Half a torus - a donut cut into a semi-circular disc.
cylinder
Half a torus. A torus is a doughnot (donut) shape.
It's a cylinder
It is a cylinder
cylinder
A cylinder has 2 circular equal opposite parallel bases
rectangle
A cylinder would not work if it wasn't circular, as its structure relies on circular bases to maintain its shape and volume. The circular cross-section allows for uniform distribution of forces and stability. If the bases were any other shape, the properties of the cylinder, such as its ability to roll smoothly or its overall structural integrity, would be compromised.
A cylinder because there are two circular bases on the bottom and top and in the middle is a curved surface. hope I helped
The question causes me to wonder how the circular bases can be defined without edges!
A cylinder would seem to fit the given description that has circular parallel bases and a rounded body.
Yes. And Its Do All Cones Have Circular Bases.
