Question

Spaceship Earth at Epcot center in Florida is 180 foot geosphere estimated volume by assuming it is a sphere with diameter 180 feet

Answer 1

the volume of a sphere = ( 4 / 3) pi r^3
when given the radius

if the diameter is given
V = ( 4 / 3 ) pi (d / 2)^3
V = ( 4 / 3) pi d^3 / 8
V = ( 1 / 6 ) pi d^3

pi = 3.1416
v = ( 1/6 )(3.1416) ( 180)^3
V = 3,053,628 cu ft
