I know what the end product is, h = A x .5b , but how do you get to it?
Sadly, no, your end product is wrong.
Here’s how to get the right answer from the formula A= 1/2 * b * h
divide both sides by b ( base length)
A / b = 1/2 [...]
I need this for a Larger Problem, but I forgot what this is. The problem is easy if I have this Formula. Can someone give it to me?
It is the sum of all its faces area , and since you have rectangle , there are 6 faces
just simply compute them and add them up
and if [...]
It don’t want a derivation related to rectangle or parllelogram because its the most basic formula and even the area of rectangle was derived from this formula. So I want a real basic derivation.
It can be derived using integration
consider a line of length dl and having a small thickness dx
the triangle can be assumed [...]
I have to find the area of a triangle, but it didn’t give me the height, just the measure of one base. But the triangle is an equilateral triangle, so is there a special formula that works for equilateral triangles?
The base is the height.

I’m doing a project on quadratic equations, and the question says, "Graph the length and area of each rectangle (length on the horizontal axis and area on the vertical axis)." I’m pretty sure that since this project is on quadratic equations, I have to graph a quadratic equation concerning the formula above, but I dont [...]
Okay the premise is that a polygon is inscribed in a circle with radius r. As n increases, the shape of the n-gon gets closer and closer to the circumference of the circle. The limit becomes closer to one.
Now the question is: What can you conclude is the formula for the area of a circle [...]
What is the formula for area of a nonogon? I know the side lengths and the apothem.
Let me try….
The formula for area of a regular polygon is A = ½ (nR²sin(360°/n)). ¼(ns²cot(180°/n)) and nr²tan(180°/n) where…
n is the number of sides
R is the radius of circumcircle
s is the length of the side
r is the apothem
I can’t [...]
Is this the correct area formula for regular pentagons? If so, what do the "s" and "n" stand for. I will pick the first answerer to help me understand it.
Yes, it is correct, but a more common formula is:
A = (1/2)ap,
where a is the length of the apothem (the distance between the center to the [...]
Ok i know it is abPI
An i also know the formula of ellipse is
(x^2/a^2)/(y^2/b^2)=1
And i use the integral of
2*PI * Y * sqrt(1+ G)
Where G is square of derivative of Y function of ellipse.
Sorry for maybe a little bit confusing explanation, but help is appreciated.
Thanks in advance.
… Total Area of Ellipse
= 4 { Area in [...]
To simplify this, couldn’t I just say that it is the area of one of the triangular faces X 8? I also need to know if this would work for a dodecahedron and an icosahedron. Thanks!!
Yes. For each of them, all faces are identical (if it’s regular, which it sounds like it is), so [...]
