Answer:
Anish performed better than Aman.
Step-by-step explanation:
Given:
Marks obtained by Aman =410
Total marks = 500
We will first find the percentage of marks obtained.
To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.
framing in equation form we get;
Percentage of Aman = 
Also Given:
Marks obtained by Anish = 536
Total marks = 600
We will first find the percentage of marks obtained.
To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.
framing in equation form we get;
Percentage of Anish = 
Now we can see;
Percentage of Anish is greater than Percentage of Aman.
Hence Anish performed better than Aman.
We know that
the perimeter of a circumference=2*pi*r
<span>If the perimeter of a sector is 4 times its radius, then the arc measure of the sector is (4r-2r)----> 2r
so
if 2*pi radians (full circle) has a length------------------> 2*pi*r
X radians -------------------------------------------> </span>2*r (the sector)<span>
X=2*r*(2*pi)/(2*pi*r)-----> x=2
the answer is
2</span>
