Answer:
The answer is "
"
Step-by-step explanation:
Please find the graph file in the attachment.
The area of its tree house's outsides of the square walls and triangular ceilings is equivalent to four squares with four triangles,
![\to A=4[(6)^2+\frac{1}{2} (6)(6)]\\\\](https://tex.z-dn.net/?f=%5Cto%20A%3D4%5B%286%29%5E2%2B%5Cfrac%7B1%7D%7B2%7D%20%286%29%286%29%5D%5C%5C%5C%5C)
![=4[36+\frac{1}{2} (36)]\\\\=4[36+18]\\\\=4[ 54]\\\\=216\ ft^2](https://tex.z-dn.net/?f=%3D4%5B36%2B%5Cfrac%7B1%7D%7B2%7D%20%2836%29%5D%5C%5C%5C%5C%3D4%5B36%2B18%5D%5C%5C%5C%5C%3D4%5B%2054%5D%5C%5C%5C%5C%3D216%5C%20ft%5E2)
You find the pattern and keep doing it.
The formula for lateral area is pi x radius x height
If the diameter is 18, the radius is 9
3.14 x 9 x 48 = 1356.48
72 degrees
