The third expression is wrong
There can be 6 teams because
27/4= 6.75
yet there will be 3 students left, so they can be a team ;)
11 836/1000. Simplified: 11 209/250.
I hope this helps! :)

Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
