Circumference/Diameter = pi = 3.14
C/D = pi = 3.14
All of these sets meet the requirements of the triangle inequality. The sum of any two numbers in the set is greater than the third one. (You really only need to check that the sum of the smallest two is greater than the largest.)
It can help to resolve the numbers that are only indicated as to value.
√13 ≈ 3.606
2√10 ≈ 6.325
_____
Your comparisons can be ...
2 + 3 = 5 > 3.606 . . . is a triangle
5 + 5 = 10 > 6.325 . . . . . . is a triangle
5 + 12 = 17 > 15 . . . . . . . . is a triangle
Ummm what? I don’t get it
The answer is $6.38 hope this helps
If you only want to know what it means ¨c¨ then it is the Denominator, cause you are referring a fraction.
