Answer:
Rounded to the nearest tenth, the volume is 1,437,773.5 cubic units.
Explanation:
First, we need to use the formula for the circumference of a sphere to find the radius:
C = 2πr
140π = 2πr
r = 70
Now we can use the formula for the volume of a sphere:
V = (4/3)πr^3
V = (4/3)π(70)^3
V ≈ 1,437,773.5
