Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
![\frac{1}{2} \times base \times height](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20base%20%5Ctimes%20height)
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
![\frac{1}{2} \times 6 \times 6 = 18](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%206%20%5Ctimes%206%20%3D%2018)
multiply this by 2
![2 \times 18 = 36](https://tex.z-dn.net/?f=2%20%5Ctimes%2018%20%3D%2036)
Now find the area of the whole circle
![area = \pi {r}^{2}](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20)
our radius is 6, therefore:
![area = \pi {6}^{2} = 113.1](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%20%7B6%7D%5E%7B2%7D%20%20%3D%20113.1)
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
![113.1 - 36 = 77.1](https://tex.z-dn.net/?f=113.1%20-%2036%20%3D%2077.1)
Step-by-step explanation:
stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation
Answer:
![f(2)=2](https://tex.z-dn.net/?f=f%282%29%3D2)
Step-by-step explanation:
So we have the function:
![f(x)=10-x^3](https://tex.z-dn.net/?f=f%28x%29%3D10-x%5E3)
And we want to find f(2).
To do so, substitute 2 for x:
![f(2)=10-(2)^3](https://tex.z-dn.net/?f=f%282%29%3D10-%282%29%5E3)
Cube:
![f(2)=10-8](https://tex.z-dn.net/?f=f%282%29%3D10-8)
Subtract:
![f(2)=2](https://tex.z-dn.net/?f=f%282%29%3D2)
And we're done!
