Spaceship Earth, a spherical attraction at Walt Disney World’s Epcot Center, has a diameter of 50 meters. Find the surface area
Black_prince [1.1K]

The surface area of Spaceship Earth is: 7850 m^2

Step-by-step explanation:

Given

Diameter of spherical structure = d = 50 meters

As the attraction is in the form of a sphere, its radius will be used to find the surface area.

Radius = r = \frac{d}{2} = \frac{50}{2} = 25\ m

The formula for surface area of sphere is:

SA = 4\pi  r^2\\= 4 * 3.14 * (25)^2\\= 4*3.14*625\\=7850\ m^2

The surface area of Spaceship Earth is: 7850 m^2

Keywords: surface area, sphere

This inequality may be written two ways:
(a) y ≥ x + 2 - 3
    or
    y ≥ x - 1

(b) y ≥ -x -2 - 3
    or
     y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

Answer: A shaded region above a solid boundary line.
