Step 1:
Given that the circumference of Spaceship Earth is 518.1 feet, we can use the formula for circumference of a circle: C = 2πr.
518.1 = 2πr
r = 518.1 / (2π)
r ≈ 82.42 feet
Step 2:
Now that we have found the radius, we can calculate the volume of a sphere using the formula: V = (4/3)πr^3.
V ≈ (4/3)π(82.42)^3
V ≈ (4/3)π(564,372.58)
V ≈ 752,496.77π cubic feet
Step 3:
The approximate volume of Spaceship Earth is 2,368,186.8 cubic feet. The unit we would use is cubic feet.
