Answer:
C=6π
Step-by-step explanation:
It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.
If identical, it means that the radius of both circles are same i.e.
![2x=\dfrac{2x+3}{2}\ \ (\because\ r=\dfrac{D}{2}, d=\text{diameter})\\\\4x=2x+3\\\\2x=3\\\\x=1.5](https://tex.z-dn.net/?f=2x%3D%5Cdfrac%7B2x%2B3%7D%7B2%7D%5C%20%5C%20%28%5Cbecause%5C%20r%3D%5Cdfrac%7BD%7D%7B2%7D%2C%20d%3D%5Ctext%7Bdiameter%7D%29%5C%5C%5C%5C4x%3D2x%2B3%5C%5C%5C%5C2x%3D3%5C%5C%5C%5Cx%3D1.5)
Radius of both circles is 2(1.5)=3
The circumference of a circle is given by :
![C=2\pi r\\\\C=2\pi (3)\\\\C=6\pi](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%5C%5C%5C%5CC%3D2%5Cpi%20%283%29%5C%5C%5C%5CC%3D6%5Cpi)
So, the circumference of each circle is 6π.
Answer:
x = 100 degrees
Step-by-step explanation:
There are 360 degrees total in this figure. Since 160 is already shown, we can subtract it from 360 to solve for x. 360 - 160 = 200. So, 200 degrees is split among the remaining values, which are 2 x's. Since each x has the same value, we can divide 200 evenly among the two of them. 200/2 = 100. So, x = 100.
P.S.: Sorry if this is long-winded, I haven't taken geometry in a while. I hope I explained it well enough for you and other Brainly users.
