What is the difference between a cylinder and a rectangle?
A cylinder is much easier and more enjoyable to place in one's anus.
Will the surface area of a cylinder increase more if you double the height or double the radius?
it will increase more if you double the radius because the dimensions multiply and the curved surface has less area to cover as its height decreases and width increases
What is the surface area of a cylinder is the circumference is 52?
You can't tell. It can be anything. A cylinder wth a circumference of 52 can have any length. It could be 0.001 long, or it could be 35 million long, or less, or more, or anything in between. All of these different cylinders could have the same circumference, but they all have different surface areas. The surface area is (circumference) x (length). So the surface area of your cylinder is 52 for every 1.0 unit it is long.
Why is the curved surface of cone not 2pi x r x l?
Because 2Pi x r x L is the curved surface of a cylinder. Clearly a cylinder have more surface area than a cone of same height and radius. The surface of the cone is Pi x r x S where S is the slope length, so the cylinder has approximately double the surface area (note S is longer than L).
What geometric shape is more efficient than rectangle for volume?
Because a rectangle is not three-dimensional it does not contain a volume but an area. A geometrical figure that is more efficient than a rectangle for area is a circle.
