So hmm notice the picture below
the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges
now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both
1] y - 3x = -8
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}

Step-by-step explanation:
pentagon , penta (five in Greek) has 5 sides and 5 interior angles
Using the assumed values, the volume of the cone is
<h3>How to determine the volume of the cone?</h3>
The volume of a cone is calculated using:
The parameters are not given.
So, we use the following assumed values
Radius, r = 5
Height, h =10
Using the assumed values, we have:
Evaluate the product
Hence, using the assumed values, the volume of the cone is
