Jim started with b baseball cards and gave 13 away. So, that means we take away from his starting amount or b.
So, b - 13 is the expression you are looking for.
a) So we know the formula of finding the circumference: 2*pi*R.
Assuming we make pi = 3.14: 2 * 3.14 * 7 = 43.96.
b) We also know the formula of finding the area: pi * r^2.
3.14 * 7^2. Using PEMDAS:
3.14 * 49 = 153.86
Answer: 78.8%
