They are expected to win back on average 50 cents back, which is a bad investment.
Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to

we have


substitute


step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians

The surface area is given by:
A = 4πr ^ 2
Where,
r: sphere radio
Substituting values we have:
2700 = 4 (3) r ^ 2
Clearing r we have:
r = root (2700/12)
r = 15
Then, the volume of the sphere is given by:
V = (4/3) πr ^ 3
Substituting values:
V = (4/3) * (3) * (15) ^ 3
V = 13500 cm ^ 3
Answer:
The approximate volume of the globe is:
V = 13500 cm ^ 3
