Find the exact circumference of the circle. please help?
1 answer:
Answer:
3rd option
Step-by-step explanation:
We first need to find the diameter of the circle.
We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.
The diagonal of a square is
where a is the side lengths of the square.
So this means the diagonal of the square is
The diagonal is also the diameter of the main circle. The formula for circumference is
where d is the diameter.
So the diameter is
or
The third option is correct

The tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.
<h3>What are the trigonometry ratios?</h3>For a right angle triangle, the trigonometry ratios can be given as,
Here, <em>a</em> is base side<em>, b</em> is perpendicular side and<em> c</em> is the hypotenuse side of the triangle.
In the given triangle, the length of base side<em> </em>is 8 units, perpendicular side is 6 units and hypotenuse side is 10 units.
Thus, the tangent, cosine and sine ratios of angles X & Y are,
Thus, the tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.
