The circumference of the Spaceship Earth at Epcot Center is 518.1 feet. Determine Spaceship Earth's approximate volume. (5 points)
Step 1: You will need to find the______ using the formula: C = 2pi*r
Step 2: You will need to substitute your answer into_____ the formula for a _____
Step 3: The answer is approximately ________ and the unit we would use is _______
Answer Choices
area
# sphere
2,350,876.75
cylinder
cone
cubic feet
582,249,550
volume
square feet
radius
1036
18,807,030
feet
Step 1: You will need to find the radius using the formula: C = 2πr
518.1 = 2πr
r = 518.1 / (2π)
r ≈ 82.38 feet
Step 2: You will need to substitute your answer into the formula for a sphere: V = (4/3)πr^3
V ≈ (4/3)π(82.38)^3
V ≈ (4/3)π(564,075.7)
V ≈ 752,100.9π
V ≈ 2,367,339.8 cubic feet
Step 3: The answer is approximately 2,367,339.8 and the unit we would use is cubic feet.
Therefore, the Spaceship Earth's approximate volume is 2,367,339.8 cubic feet.
