Since you are given the area, we can solve for radius with this equation:
![A_c = \pi r^2](https://tex.z-dn.net/?f=A_c%20%3D%20%5Cpi%20r%5E2)
![r = \sqrt{ \frac{A_c}{ \pi } } = \sqrt{ \frac{121 \pi }{ \pi } } = \sqrt{121} = 11](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%20%5Cfrac%7BA_c%7D%7B%20%5Cpi%20%7D%20%7D%20%3D%20%5Csqrt%7B%20%5Cfrac%7B121%20%5Cpi%20%7D%7B%20%5Cpi%20%7D%20%7D%20%3D%20%5Csqrt%7B121%7D%20%3D%2011%20)
The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
For this case, the first thing we must do is define a variable.
We have then:
x: number of weeks
y: amount of cereal that Melanie eats
We now write the function that models the problem:
![y = 1.5x ](https://tex.z-dn.net/?f=y%20%3D%201.5x%0A)
Then, for 5 weeks we have:
Answer:
A model that best represents the number of pounds of cereal she eats is:
For 5 weeks we have:
I believe you multiply by V
Answer:
The probability of drawing two spades is 3/51. Hope this helps!!
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
a = the other leg:
![a^{2} =(2\sqrt{3} )^{2} -(\sqrt{3}) ^{2} =(4)(3)-3=12-3](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%3D%282%5Csqrt%7B3%7D%20%29%5E%7B2%7D%20-%28%5Csqrt%7B3%7D%29%20%5E%7B2%7D%20%3D%284%29%283%29-3%3D12-3)
![a^{2} =9](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%3D9)
![a=\sqrt{9}](https://tex.z-dn.net/?f=a%3D%5Csqrt%7B9%7D)
![a=3](https://tex.z-dn.net/?f=a%3D3)
Hope this helps
