Is pipe round because it provides the least surface area to volume ratio?

More likely because it's easier to manufacture, much easier to put threads on, you don't have to worry about orientation when you put them together, and they have no weak spots created by corners.
My gutter pipes are rectangular because they don't stick out as far from the house as a circular one with the same area. But they are low enough in the pressure they contain that they can be formed from sheet metal with a crimped seam. Making a water supply pipe that way would be impossible.
And it's easy to keep them aligned to the house. Running a rectangular water main under a street would be a major pain.

Can a Boeing fly with one engine?
No. It cannot fly with one engine, because it is very heavy.It must have at least two engines to stay in air.
Why do you need to find the natural ground level when building?
Here is what the IRC (International Residential Code) says about footings and proper placement. R403.1.4 Minimum depth. All exterior footings shall be placed at least 12 inches (305 mm) below the undisturbed ground surface. The basic reasoning for getting down to natural ground level is to get to get below the level of undisturbed ground surface. This includes the ground surface likely to include roots and other bio materials. Undisturbed ground is more likely to properly support the weights applied from a structure over the long term. Take for instance tree roots
How matrices can be represented using two dimensional array?
You've pretty much answered your own question because a two-dimensional array is a matrix. Indeed, all multi-dimensional arrays are matrices. When we create a matrix, we generally know what type of data will be stored in the matrix, how many dimensions it will have and how many elements each dimension will have, thus an array is the ideal container to represent a matrix. It provides the most compact method of storing homogeneous data, provides efficient constant-time random access to the data and introduces the least amount of abstraction into the representation. Most languages do not provide a built-in matrix type, however this is simply because there is no one matrix type that would suit every possible application. However, all languages do provide a built-in array mechanism which can be used as the basis for any matrix type which is both simple to create and easy to maintain.
How do you get a big volume with the least surface area?
The maximum volume with the least surface area is enclosed in a sphere.That's why soap bubbles, balloons, and stars settle into spherical shapes.
What shape has the most surface area?
least volume and most surface area is 3D triangle
What shape would have the least Surface Area and the most volume?
A circle
Will an equilateral triangular prism have the least amount of surface area?
No. Relative to its volume, the greater the number of sides, the smaller the volume. In the limit, a cylinder (circular prism, with an infinite number of "sides") will have the least surface area.
Why do cats curl up into a ball when cold?
It has to do with volume vs surface area. All things lose heat through the surface. The bigger the surface, the more heat lost. An animal curled into a ball presents the least amount of surface area for its volume, which means it takes the least amount of energy to keep warm.
How is a sphere different from other 3d figures?
It has no vertices. It has the least surface to volume ratio. It has infinite axes of symmetry.
What provides the least magnification in the microscope?
The coarse adjustment provides the least magnification because it only focuses big parts whereas the fine adjustment focuses on little details.
Why are spheres important?
well each and every geometrical figure has its own importance. Spheres have the least surface area for a given volume compared to any other object of same volume.
Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
Which item below provides the least detailed information about the surface of the earth?
The globe cuz all it shows is the earth and its contenents no mountains or lakes.
How do you measure the volume of 10m length cylinder?
You must know at least one other dimension, such as diameter or surface area before this can be answered.
What makes a water drop round instead of flat?
A water drop is a perfect sphere. A sphere is the geometrical shape that has the smallest surface area for its volume. The drop takes this shape because water molecules tend to stick to each other.
