Why does the formula of a cylinder for volume work?
Pretend you have a soup can in front of you. That is a cylinder. Now, pretend you are cutting off both ends, which are circles. Now, with the leftover body part, unfold it, so it resembles a rectangle. Now you have circles and triangles. Now, use the rectangular area formula (Area=Base X Height) and find the area of the rectangle. Now, use the circular area formula (Pi [3.14] X Radius [Half the diameter]2) and multiply that by 2 (because of the 2 circles, top and bottom). Add the rectangular and circular (the doubled total) together and you have the area of the cylinder. I hope this helped!
How do you work out the interior angles and area of a triangle that has sides of 2cm 3cm and 4cm?
Use the cosine ruleref: http://www.bbc.co.uk/schools/gcsebitesize/maths/shapes/furthertrigonometryhirev2.shtmlImproved Answers:-Sketch a triangle and label the vertices A, B and C then label the opposite sides a, b, and c respectively with the given dimensions.Use: cos A = (b2+c2-a2)/(2*b*c) then rearrange the formula to find the other angles or use the sine rule.For the area use: 1/2*b*c*sin AA = 104.4775122 degeesB = 46.56746344 degreesC = 28.95502437 degreesArea = 2.904737751 square cmUsually the above figures are rounded off to about 3 decimal places
What is the formula for a semi-circle?
There is no formula for a semicircle. There is a formula for the perimeter of a semicircle, a different formula for the area of a semicircle, and another one to generate a semicircle in the Cartesian plane. You must specify which of these you want a formula for. Also, there may be additional information that is required to put the formula in the context of the available information. For example, the formula for the area will differ depending on whether you know the length of the straight side or the semi-circular arc.
How do you find the unknown height of a trapezoid if the bases are 27cm and 31 cm and the area is 348cm2?
You can cut the tapered ends off of the trapezoid, and calculate the individual areas of the three pieces. The center piece is a rectangle, Length = 27, Height = H. Area = 27H. Each end is a triangle, Base = 2, Height = H. Area = (1/2 base) times (height) = 1H (Left-end triangle) + (center rectangle) + (right-end triangle) = 1H + 27H + 1H = 29H. 29H = 348 cm2 H = 348/29 = 12 cm
What is the surface area of a nickel in cm?
First off, area is in square cm while distance is in cm. The radius of a nickel is 1.0605 cm, so using the famous formula pi x r2 for the area gives: 3.141593 x 1.06052 = 3.5332 cm2
What is the surface area of an isosceles triangle?
i is usually 1/3 of the area but if you want to find the area off a certain
How do you find the formula of the surface area of A SQUARE PYRamid?
I'm not sure, but I think you would find the are of the base and find the area of one of the triangles and multiply the triangle one by four...I am basing this off of my 5th grade math lessons in surface area, so this may not be accurate...but you can try it and find out for me! :D
What happens in the bremuta triangle?
The Bermuda Triangle is an area in the Atlantic ocean off the coast of Florida where many unexplained dissappearances occured, the most famed being the dissappearance of Flight 19.
Did the Bermuda triangle have anything to do with the Illuminati?
No. There is no connection between the Bermuda Triangle and the Illuminati. One is the name given to an area off the eastern coast of Florida. The other is a fictional secret society.
What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.

What is the area of a circle that has a radius of 13.0?
the formula for finding the area of a circle is pi*r^2 or read as pi,rsquare. answer is 531, rounded off to the nearest whole number.
How is a formula affected if the syntax is off?
The formula may not work properly, and more than likely it may not work at all. It is important to follow the syntax and know how to use the formula and any functions that are in it. It is the functions that have a stronger structure of syntax, and getting syntax wrong can cause lots of problems.
