C=2πr
c/2π=2πr/2π divide both sides by 2π
c/2π=r
Therefore r=c/2π

Answer:
6 rides
Step-by-step explanation:

Justin has enough on his bus card for 6 more rides.
Answer:
x>11
Step-by-step explanation:
To simplify this inequality, we add 3 from both sides to get x-3+3>8+3. Since -3+3 cancels out to 0, we are left with x>8+3. 8+3=11 so x>11.
