To work out the area of a composite shape, you will have to divide it into smaller figures.

Area = 0.5*(sum of parallel sides)*height

You can't derive the volume from the surface area.

Area of a trapezoid: 0.5*(sum of parallel sides)*height

A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.

There is no information on the shape of the area in question.

All you have given is a rectangle which I presume encloses the composite shape. It is impossible to give the area of the composite shape other than to say it is less than or equal to 8 sq units. To work out the area of a composite shape, split it up into areas which you can work out (eg squares and rectangles) and sum the area of all the area.

Second moment of area for triangle trough x-axis = (ah3)/36

It is: 0.5*(sum of its parallel sides)*height

mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis

There is no single formula, unless you consider the following:Sum(Area of each part of the composite shape calculated according to its bus-formula).

A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.

Not easily. You need to find the area or perimeter of the components and sum them.

Not really. While there is nothing that would prevent a composite volcano from developing under an area where a pond happens to be, there is no pond big enough to contain a composite volcano. As soon as the volcano starts forming, the first significant eruption would probably fill in or blast away the pond.

To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.

it is a composite number and area is divided by 1,11,17

There are two types of moments of inertia - one is mass moment of inertia and the other geometrical or area moment of inertia. The geometrical moment of inertia is cross sectional property of an area that is used to compute stress and deflection in structures. It is the the integral of square of the distance to the centroid axis over the area cross section.

The cube's surface area consists of six squares; you can simply add the area of each of the squares. Note that each of the squares has the same size.

Yes, it is the unit for distance and can be used to derive those for volume and area.

A person cannot determine the area of a shape without a formula for a composite figure. A formula must always be implemented in order to properly come with an equation.

Break it down into smaller shapes, find the area of those bits, then add them all together.

If you mean 37 and 6 then they area prime and a composite number respectively If you mean 376 then it is a composite number because it has more than two factors

I = pi (do4 - di4) / 64

-find the area(A) of the shape above the neutral axis (or above a particular point if given) - locate the centroid (y')of the shape relative to the neutral axis(or above point) using y' = ∑AiYi / ∑Ai - first moment of area = A*y' (or y' + distance of given point from neutral axis)

To derive the cross sectional area of a two liter bottle do the following formula. Area = (radius * 2.54 cm/in)^2 * pi = X cm^2.
