Answer:
The first choice
Explanation:
Because there is a closed dot, you need to use either less than or equal to or greater than or equal to. And because it’s pointing to left and getting smaller, d is less than or equal to 5.
Since the formula for the area of a circle is Pi x r squared, the area would be 81 x Pi (you teacher may want you to use Pi as 3.14 or put it in your calculator).
The answer is Radical 6.
This is because if you use Cosine and the angle measured 30. You would put adjacent over hypotenuse, which is
Cos (30) = X/radical 8
Put this into your calculator to get Radical 6
