Step-by-step explanation:
The formula for circumference is
The diameter is double the radius, so to get the radius we divide by 2.
5 divided by 2 is 2.5
Knowing "r" is 2.5 we can plug that into our equation and solve.
2 · · 2.5 ≈ 15.71
2/9 times
This is because 2/5 divided by 9/10 = 10/45 wich if we simplify it we get 2/9 so that's why 2/9 is the right answer.
