C=2pr, r=c/(2p)
a=pr^2, using r found above we get:
a=p(c^2/(4p^2))
a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14
a=(106.76^2)/(4*3.14)
a=11612.2176/12.56 cm^2
a≈924.54 cm^2 (to nearest one-hundredth of a square cm)

Answer:
she bought 8 coach, 2 first-class
Step-by-step explanation:
let x = number of coach tickets
equation I used: 320x + 960(10 - x) = 4480
320x + 9600 - 960x = 4480
-640x = -5120
x = 8
