How do you calculate cross sectional area of bar?
It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
What is the area of a complex figure with a perimeter of 112 feet?
Anywhere between 0 square feet and approx 998.2 square feet - it all depends upon the exact shape of the complex figure. To calculate the area of a complex figure, split it up into shapes for which you can workout the area and then add all the areas of the shapes together.
How do you calculate the area of a complex shapes?
It depends partly on the nature of the complex shape. Some complex shapes can be decomposed into smaller shapes whose areas can be determined using standard formulae. It is the simply a question of adding the parts together.For more complicated shapes, there are essentially two options: you can either use uniform laminae and mass or estimate the area using grids.Uniform Lamina: Copy the shape onto a sheet (lamina) of material with uniform density. Cut the shape out carefully and measure its mass (or weight). Do the same for a unit square of the lamina.Then, because the lamina is of uniform density, the ratio of the two areas is the same as the ratio of the two masses.That is: Area of Shape/Area of Unit Square = Mass of Shape/Mass of Unit Square =Rearranging, and noting that the area of the Unit Square is, by definition, = 1 sq unitArea of Shape = Mass of Shape/Mass of Unit Square.Grid Method: Copy the shape onto a grid, where each grid square has an area of G square units. Count the number of squares that are fully or mostly inside the shape. Call this number W (for whole). Count the number of squares that are approximately half inside the shape and call this number H (for half). Ignore any square that are less than half in the shape.Then a reasonable estimate of the area of the shape is G*[W + H/2] square units. There is some arbitrariness about "mostly inside" and "approximately half" but there is no way around that. You will get more accurate results with finer grids, but they will also require much more effort in terms of counting the grid squares.
What are the solutions of rational algebraic equations?
They can be rational, irrational or complex numbers.They can be rational, irrational or complex numbers.They can be rational, irrational or complex numbers.They can be rational, irrational or complex numbers.
Find the complex number that is farthest away from the complex plane?
All complex numbers are part of the "complex plane", so none of them is farther than others.
