What is the best approximation for the area of this circle?
2 answers:
Answer: [C]: 50.2 m<span>²
__________________________
Since: Area of a circle: A = </span>
* r² ';
And: A = = 3.14 * 4² = 3.14 * 16 ;
We know that the area will be a bit more that ( 3 m * 16 m = 48 m²) ;

And, Answer choice: [C]: 50.2 m² ; is the closest value.

General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
sin 30°
<u>Step 2: Solve</u>
Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.
Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.
Substituting it into sin, we have:
sin 30° = 1/2 = 0.5
∴ our answer is A.
The polynomial that represent twice the sum of - x +6 and 7

<h3>What is a polynomial?</h3>
A polynomial is any algebraic expression that has the least value of the power of its variable as 2.
When the highest value of the polynomial is 2, it is a called a quadratic expression.
Analysis:
2( -5 -x +6 + 7
+x -1)
2( 2 + 5) =
4 + 10
In conclusion, the polynomial that represents the above expressions is 4 + 10
