Without another piece of information, the radius alone isn't enough to tell you the volume of the cone. You really need the height too.
No. The square is all on one flat surface, like a piece of paper, but a cube has height off of the paper. When you set the cube down on the piece of paper, the place where it touches the paper is a square, but there's a lot more to it than that.
The height of a normal letter-size paper (also known as US Letter) is 11 inches, while the width is 8.5 inches.
The height of a piece of paper folded in half once is half of its original height.
no it is not a physical change because folding a piece of paper does not chemicaly change it.
Physical change
A piece of paper rolled into a cylinder lengthwise would have a greater volume because it would have a larger radius compared to one rolled into a cylinder widthwise. The volume of a cylinder is maximized when the radius is maximized, which occurs when the paper is rolled lengthwise.
Coloring on a white piece of paper is a physical change because the color change is reversible and does not alter the chemical composition of the paper. The paper remains paper even after coloring on it.
When you crumple a piece of paper, a physical change occurs. The paper's shape and appearance change, but its chemical composition remains the same.
tearing a piece of paper is a physical change because when you rip it,it is still a piece of paper but lets say that u burn a piece of paper its a chemical change couse you cant change it back to wood again

Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
Folding the piece of paper does not change the thickness of the piece of paper. However, the thickness of the folded paper would be twice that of the original sheet of paper.
Physical- it is still a piece of paper. It can be unwadded. But if you burned it (a chemical change) it is no longer paper, and you cannot unburn something.
