Step 1: Find the circumference of the circle
Formula for circumference: C = 2 * pi * r
C = 2 * pi * 27
C = 54pi
Step 2: Find the length of the desired arc
We are only looking for 20 degrees out of 360 degrees, therefore we can multiply our circumference by 20/360.
20/360 * 54pi = 3pi units
Hope this helps!

![8x[(7+4)x^2] - [(11-7)x^4]\\ \\ 8x[(11)x^2] - [(4)x^4] \\ \\ 8x[11x^2] - [4x^4] \\ \\ 88x^3 - 4x^4 \\ \\ -4x^4+88x^3](https://tex.z-dn.net/?f=8x%5B%287%2B4%29x%5E2%5D%20-%20%5B%2811-7%29x%5E4%5D%5C%5C%20%20%5C%5C%208x%5B%2811%29x%5E2%5D%20-%20%5B%284%29x%5E4%5D%20%5C%5C%20%20%5C%5C%208x%5B11x%5E2%5D%20-%20%5B4x%5E4%5D%20%5C%5C%20%20%5C%5C%2088x%5E3%20-%204x%5E4%20%5C%5C%20%20%5C%5C%20-4x%5E4%2B88x%5E3%20)
If you then want to go on to factor it, your answer would be
The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!
