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 [...]
the volume of an ellipsoid is: 4 π a b c / 3.

We know that for a triangle in 2d, area =
| 0.5 0.5 0.5 |
| x_1 x_2 x_3 |
| y_1 y_2 y_3 |
Is there a similar formula for triangles in space, with points given as (x,y,z) coordinates?
The 2d determinant formula generalizes in 3d to a determinant formula for the volume of a tetrahedron. [...]
I am in grade 7 and i was wondering what the formula for surface area of a triangular prism. thx ( and please explain it easily )
A triangular prism is a 3-dimentional object with 2 triangular bases and three rectangles connecting the bases.
Find the area of the triangle A = bh/2, but there [...]
Knowing the formula for the area of a rectangle, how could I show why the formula for the area of a parallelogram is A= b*h?
by the way I am 13 so try not to use complicated language! thanx
Cut a triangle off of the parallelogram… so that the parallelogram becomes a right trapezoid and the [...]
I don’t want u to explain to me how to do it. But please just give me the FORMULA of the surface area of a rectangular prism. Please (:
And the volume formula please.
The volume of a pyramid:
V(volume) = 1/3 * Area of the base * Height
The surface area of a pyramid:
SA(surface area) = [1/2 * [...]
i believe it is a triangular pyramid. all sides and the base are triangles so if it something else, please tell me.
Just find the area of all of the triangles, then add it up
Hey i need to know how to do the formula to get the area of a pyramid
