Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
$46
100% of 40 is 40. 10 percent of 40 is 4. 5% of 40 is 2. 40+4+2=46.
2: 4 is a factor and multiple of 8. 8 and 4 is also even numbers so is is most likely to be divisible by any number
