Answer:
42.7 in^3 of the interior space is occupied by blue water
Step-by-step explanation:
1. Find the volume of the ball.
2. Take 85% of this volume.
Volume of a sphere: V = (4/3)(pi)(radius)^3
Here this volume is V = (4/3)(3.14)(125 in^3), or 50.24 in^3
85% of this volume is 0.85(50.24 in^3) = 42.7 in^3
42.7 in^3 of the interior space is occupied by blue water.
