Ans n solution can refer in the picture
0.1 0.2 because its only sum of only 0.3
Perimeter: 9+9+8+8= 34 ft.
Area: 9*8= 72 ft²
The graphs arey=(1/3)x^2
and y=3
they intersect at x=3
so the limits are x=0 and 3
to rotate it about y=k, minus k from every function
![area=\pi \int\limits^3_0 {( \frac{1}{3}x^2-3)^2-(3-3)^2 } \, dx](https://tex.z-dn.net/?f=area%3D%5Cpi%20%20%5Cint%5Climits%5E3_0%20%7B%28%20%5Cfrac%7B1%7D%7B3%7Dx%5E2-3%29%5E2-%283-3%29%5E2%20%7D%20%5C%2C%20dx%20)
which evaluates to 72/5pi
