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.
The formula for surface area of sphere is:

Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to
m =
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (r, - 4)
m = =
, then equating gives
=
( cross- multiply )
3(r - 3) = - 12 ( divide both sides by 3 )
r - 3 = - 4 ( add 3 to both sides )
r = - 1 → B
Answer:
The only equation which is incorrect is in option B.
Step-by-step explanation:
Eva used the following equation in order to solving integers, which is
⇒ ......... (1)
Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.
Now, in option A) it is given that
⇒ which is same as equation (1).
In option B) it is given that
⇒ which is not same as equation (1).
In option C) it is given that
⇒ which is same as equation (1).
Again, in option D) it is given that
⇒ which is same as equation (1).
Therefore, the only equation which is incorrect is in option B. (Answer)
