Answer:
The shaded region is
.
Step-by-step explanation:
The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply
.
15m is the radius of the large circle, and also the diameter of the smaller circles.
The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.
As such:
![A=\pi(15)^{2}-2(\pi(\frac{15}{2} )^{2})\\\\A=(3.14)(15)^{2}-2(3.14)(\frac{15}{2} )^{2}\\A=706.5-353.25\\A=353.25](https://tex.z-dn.net/?f=A%3D%5Cpi%2815%29%5E%7B2%7D-2%28%5Cpi%28%5Cfrac%7B15%7D%7B2%7D%20%29%5E%7B2%7D%29%5C%5C%5C%5CA%3D%283.14%29%2815%29%5E%7B2%7D-2%283.14%29%28%5Cfrac%7B15%7D%7B2%7D%20%29%5E%7B2%7D%5C%5CA%3D706.5-353.25%5C%5CA%3D353.25)
Step-by-step explanation:
Surface area of a square pyramid is the area of the square base plus the area of the four triangles made from the base and the slant height.
SA = s² + 4(sh/2)
which reduces to:
SA = s² + 2sh
You are told that s = 11 and SA = 319. You can now solve for h:
319 = 11² + 2(11)h
319 = 121 + 22h
198 = 22h
h = 9 ft (answer C)
