The Epcot Center in Florida has a giant dome that is a sphere with a diameter of 165 feet. Which value is closest to the volume of the dome? Use 3.14 for π.

Selected Answer:

Correct 2,350,879 ft3

Correct Answer:

Correct 2,350,879 ft3

Answer 2

The volume of a sphere is 4/3(pi)r^3
To find the radius we do the diameter divided by 2 - 165/2=82.5
4/3(pi)(82.5)^3
We get 2,350,879 when we multiply it together, so your answer is 2,350,879 ft^3
