Answer:
The answer to your question is ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
Here, there is a difference of squares, so just solve it and simplify
![( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )](https://tex.z-dn.net/?f=%28%201%20%2B%20%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%20%7D%20%29%20%281%20-%20%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%20%7D%20%29)
Multiply the binomials
= 1 - ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Simplify
= ![\frac{3 - 1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%20-%201%7D%7B3%7D)
= ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)

Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
