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

Answer:

The surface area of the structure is $SA=2,500\pi\ m^{2}$

Step-by-step 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

$SA=4\pi (25)^{2}$

$SA=2,500\pi\ m^{2}$
