Answer:
arc AB = 60°
Step-by-step explanation:
The diameter splits the circle into two semi circles.
in the semicircle above the diameter, you can do 180° - 120° = 60°
so arc AB = 60°
( I'm sorry; I'm not sure how to get the answer in terms of pi. )
Answer:
See below
Step-by-step explanation:
Expand it a bit to see:
= ![\sqrt[5]{ 2^5 * 7 * x^5 * x^5 * x * y^5 * y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%202%5E5%20%2A%207%20%2A%20x%5E5%20%2A%20x%5E5%20%2A%20x%20%2A%20y%5E5%20%2A%20y%5E3%7D)
=![2x^2y \sqrt[5]{7xy^3}](https://tex.z-dn.net/?f=2x%5E2y%20%5Csqrt%5B5%5D%7B7xy%5E3%7D)
8 / 6.403 = 1.249...
nearest tenth = 1.2
