the answer is -2 because 21-23 is a negative number
Basically it’s r=c/2pi meaning it’d be r=62/2(3.14) which would give you r=9.87
Answer:
C) r3 < r2 < r1
Step-by-step explanation:
Answer:

Step-by-step explanation:
We need to find which statements are true.
Solution to find the same we will solve each statement and will conclude the same.
1. 
Now On solving we get;


So we can see that 0.70 > 0.66
Hence The given statement is False.
2. 
Now On solving we get;


So we can see that 0.5625 > 0.5
Hence The given statement is True.
3. 
Now On solving we get;


So we can see that 1.33 > 1.2
Hence The given statement is False.
4. 
Now On solving we get;


So we can see that 0.82 > 0.66
Hence The given statement is False.
