Answer:
18.84 inches.
Step-by-step explanation:
Volume = 4/3 π r^3 = 113.04
r^3 = 113.04 / 4/3 * 3.14
r^3 = 27
r = 3 inches,
So the circumference = 2 * 3.14 * 3
= 18.84 inches.
Answer: A
Step-by-step explanation:
The answer is A.
y≤-2x+3 .... (1)
y≤x+3 ..........(2)
In the system is inequality above, the f(x) is a negative graph while the g(x) is a positive graph.
The two function have different gradients ( slope) so, the will surely have the intersecting portion or area where f(x) and g(x) have shading in common which is labeled AB.
ANSWER
![12\pi \: {cm}^{2}](https://tex.z-dn.net/?f=12%5Cpi%20%5C%3A%20%20%7Bcm%7D%5E%7B2%7D%20)
EXPLANATION
We want to find the area of the shaded region.
We find the area of the smaller circle and subtract from the area of the larger circle.
Area of smaller circle is
![a = \pi \: \times 2^{2} = 4\pi](https://tex.z-dn.net/?f=a%20%3D%20%5Cpi%20%5C%3A%20%5Ctimes%20%20%202%5E%7B2%7D%20%20%3D%204%5Cpi)
Area of larger circle is
![A = \pi \: \times {4}^{2} = 16\pi](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20%5C%3A%20%20%20%5Ctimes%20%7B4%7D%5E%7B2%7D%20%20%3D%2016%5Cpi)
The area of the shaded region is:
![16\pi - 4\pi = 12\pi](https://tex.z-dn.net/?f=16%5Cpi%20-%204%5Cpi%20%3D%2012%5Cpi)
The answer to your question is 5/9.
I believe the correct expression would be: x * 70%
You should double check, and I hope this helped you! =)
