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

Answer:

h=12 A=144 sq. cm.

Step-by-step explanation:

pythagoream therom:

9^2+h^2=15^2

81+h^2=225

h^2=225-81

h^2=144

Sq. rt h^2=sq. rt 144

h=12cm

1/2(b1+b2)h

1/2(5+19)12

1/2(24)12

1/2(288)

a=144
