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

If the re-expressed regression line is ln y = 8.7 + 0.23x, what is the value of y when x is 12?

Sauron [17]

Answer:

y=11.46

Step-by-step explanation:

$y = 8.7 + 0.23x \\ y = 8.7 + 0.23(12)$

$y = 8.7 + 0.23 \times 12 \\ y = 8.7 + 2.76$

$y = 11.46$

$to \: multiply \: 0.23 \times 12 \\ you \: convert \: the \: decimal$

$= 23 \ \times 12 \div 100 \\ = 276 \div 100$

$= 2.76$
