You could use ratio to figure this out.
6:9 = 15
6 baseball for 9 football cards
Divide the total by the amount already known
60/15 = 4
Multiply all values by 4.
6 x 4 = 24.
9 x 4 = 36.

In short, the answer is 24.

Hope This Helps You!
Good Luck Studying ^-^

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units
