the solid is made up of 2 regular octagons, 8 sides, joined up by 8 rectangles, one on each side towards the other octagonal face.
from the figure, we can see that the apothem is 5 for the octagons, and since each side is 3 cm long, the perimeter of one octagon is 3*8 = 24.
the standing up sides are simply rectangles of 8x3.
if we can just get the area of all those ten figures, and sum them up, that'd be the area of the solid.

Step-by-step explanation:
If the corner of your porch is the origin
- 4 ft to the left, x=-4
- 5 ft in front, y=5
The tree's location is at (-4,5).
- A circular fence 3 ft in radius has its center at the tree(-4,5).
We want to determine the equation of a circle with center (-4,5) and radius 3 ft.
The equation of a circle center (h,k) with a radius of r is given as:
(h,k)=(-4,5), r=3
The equation formed by the fence therefore is:
