Parallel because congruency and parallelism is somehow similar and that word fits in perfectly
Answer:
![A=5.29\pi](https://tex.z-dn.net/?f=A%3D5.29%5Cpi)
Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
<em>Given circumference of the ring is
</em>
<em>Now solving for the radius gives us:</em>
![2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3](https://tex.z-dn.net/?f=2%5Cpi%20r%3D4.6%5Cpi%5C%5Cr%3D%5Cfrac%7B4.6%5Cpi%7D%7B2%5Cpi%7D%5C%5Cr%3D%5Cfrac%7B4.6%7D%7B2%7D%3D2.3)
We know that area of a circle is
, substituting the value of r we found, we get the area as:
area (A) = ![\pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%5C%5C%5Cpi%20%282.3%29%5E2%5C%5C%5Cpi%20%285.29%29%5C%5C%3D5.29%5Cpi)
Hence the Area (A), in terms of
is
Answer:
B. No solutions
Step-by-step explanation:
8x+2y=14
8x+2y=4
These linear equations are in standard form, and the Ax values are the same (8x) and the By values are the same (2y). The only value that is the different is the C values (14 and 4), which will be the cause of a no solution for this system of equations.
For example, exc. 15.
x + y = 10 and 6/x = 9/y; You need y!
=> x = 10 -y and 9x = 6y => 9(10-y) = 6y => 90 - 9y = 6y => 15y = 90 => y = 6.
