How do I calculate the area for an irregular shape?
99265
I asked that same question to my teacher last time. She told me that I have to Seperated the shape into different common shapes. (for example like lets say I wanted to seperate a "square" into some common shapes I could turn it into two seperate triangles or four different triangles. Well Just try to use the formulas you know for the areas of the different disected figures you get.

Assuming you have a rectangular object, then L x H x W will work. For other shapes you need something else. See sources.

you need to use some calculus.\nget an expression for the area \ndifferentiate it\nthen find when it is a maximum.

area of a regular hexagon=3rt3/2 *a^2\n=3rt3/2*24^2\n=72*12rt3\n=864rt3 cm^2

rare gem's answer is right..given the radius you'll just need to compute for the area using the formula right?\n\nArea=(radius^2)(pi)\n    = (5)(5)(pi)

square-ish in shape\ncome in different sizes\nmany varieties

It sounds to me like you are talking about a trapezoid. Go to the website I have listed under my sources and see if what you are describing looks like the trapezoid on there. If it is a trapezoid, the area formula is  Area = 1/2h(b1 + b2). h=height, b1=base 1, b2=base 2

area = 1/2 x base x height

Find the areas of all 6 faces of the rectangular solid by muliplying each one's width by length.  Then add them together for the total surface area.  To find volume, multiply length by width by height.  The ratio will be the total surface area divided by the volume (or expressed as a fraction the total surface area over the volume).

It all depends on the shape you are trying to measure. Different shapes use different equations.\n\nSurface area is generally quite easy. you just work out the area of each side and add them all up. Try this site: http://www.bbc.co.uk/schools/gcsebitesize/maths/shape/arearev3.shtml\n\nVolume is a little more difficult. There are some good examples of working out volumes of different shapes here: http://www.bbc.co.uk/schools/gcsebitesize/maths/shapeih/areaandvolumerev3.shtml

It is similar to calculating the area. \n\nIt is a product of Length and Width (L x W).

2 X pi X  r = cirumference\n\npi X r squared = area

Imagine you unraveled the cylinder, the middle would turn into a rectangle, right? so to find the surface area, take the height of the cylinder and multiply it by the circumference of the circles at the bases, then add in the area of the circles. Circumference is 2(pi)r and area is (pi)r^2.

You need to know the base and the height of the shapes. \n\ntrapeziod: average of two bases x height\nparallelogram: base x height\ntriangle: 1/2 x base x height\n\nOr if you know how to use the sin, cos, tan, then you only need to know a few sides to calculate the base and the heights.

area=(1/2)d1*d2\n=(1/2)*28*13\n=14*13\n=182 sft

You have to find an area.  If ou have one foot by one foot, it is one square foot.  If the area is circular, find the area of the circle.

Well area is equal to Radius squared times 2 pie(or22/7)\nSo you would have 35^2=1225 and then 1225*2*(22/7)=7700 inches for your area\n\nhope that helped
