-i tried looking for it online but it only gives me the volume and the area formula for a square.
The surface area of a cube is S = 6s^2.
You can see this because the surface area is just the area of all of the faces. Since each of the six faces on the cube [...]
To find the lateral area of a regular pyramid I am given the formula LA = 1/2 pl. What in the world is pl? I do not understand!
p is the perimeter of the base
l is the slant height, which is the distance from the vertex to a midpoint of a base.
i seen so many different formulas for surface area of a cylinder, but im just plain confused on which is what, and now i dont know how to solve for the radius. Please Help
i have the volume which is 390 cm^3
The area of the ends of the cylinder is just the area of the circle [...]
so, i know that it’s the apothem/2 , times the perimeter of th figure.
why does this formula work in finding the area?
In a regular polygon, the apothem is perpendicular to each of the sides. Therefore you could divide the polygon into n separate triangles, with the center of the polygon as one point and each [...]
Why are the area formula for a square and the area formula for a rhombus only equal when the angles are all 90 degrees?
You seem to be labouring under a serious misapprehension. Of course you can use the rhombus formula for a square. There are several formulae which are used for the rhombus [...]
Does anyone know? I can’t seem to find it on Google. Please help, and thank you♥(:
surface area = base area + lateral area = a^2 + 4aL, where a is the side length of the base, and L is the slant height of the pyramid.

Attn: You want a formula which should contain the slant height. [...]
area formula of the radius is A = Pi(r)^2
so what would it be for the diameter?
diameter is 2 x the radius (2r)
Ok so I need to know this. You know how the area of a triangle is 1/2basexheight I need to find some formula like that.
The formula for the area of an arbitrary quadrilateral is
√[(a+b+c-d)(a+b-c+d)(a-b+c+d)(-a+b+c+d) - 16 abcd cos(q)^2]
where q is half the sum of two opposite angles. For a cyclic
quadrilateral the each pair of [...]
I need to know the history and who created the formula for lateral area. (LA = Perimeter of base x Height) Please help me !
Surely the ancient Greeks knew this 2000 years ago. Check in Euclid.
I think of it as cutting the ends off the can and then slicing through the rest of the can so it can be laid out flat to form a rectangle. The area of the circular ends is pir^2 each and the area of the rectangle is LW where the width is the height [...]
