Answer:
52.33% is the correct answer.
Step-by-step explanation:
<u>Given that:</u>
Area of triangle = 24 sq units
Center of Circle is at <em>(0, 0)</em> and the circle passes through <em>(1.2, 1.6).</em>
<u>To find:</u> The percentage of triangle covered by circle.
<u>Solution:</u> To find the required percentage, we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
We can use Distance formula :
Radius =
Now, area of circle is given by the formula:
Area =
Area = 3.14 = 12.56 sq units
Percentage of Triangle covered:
Hence, 52.33% is the correct answer.
In attached file you can see Pascal's triangle. Explanation for this triangle is following:
- coefficient in 0th row is
- coefficients in 1st row are coefficients of
- coefficients in 2nd row are coefficients of
- coefficients in 3rd row are coefficients of
and so on
- coefficients in 6th row are coefficients of
Then
Simplify it:
