Question

Spaceship Earth, a spherical attraction at Walt Disney worlds epcot center, has a diameter of 50 meters. Find the surface area of the structure. (JUSTIFY)

Answer 1

The surface area of the structure is
`SA=2,500\pi\ m^(2)`

Explanation:

we know that

The surface area of a sphere is equal to

`SA=4\pi r^(2)`

In this problem we have

`r=50/2=25\ m` -----The radius is half the diameter

substitute

`SA=4\pi (25)^(2)`

`SA=2,500\pi\ m^(2)`
