Answer:
The dollar bills would encircle earth 65753.1 times
Step-by-step explanation:
We have
Length of dollar bill = 15.5 cm
Total dollar bills = 17 trillion =
Thus the length of 17 trillion dollar bills equals
Now taking shape of earth as a perfect sphere the circumference of earth becomes
Thus the number of times the dollar bills would encircle earth equals

This is a circle with center (h, k) at (0,0) and radius (r) = 6
Formula: (x - h)² + (y - k)² = r²
Answer: x² + y² = 36
