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.
