Answer:
803.84 feet squared
Step-by-step explanation:
A=pi*r^2
16^2=256
256*pi=803.84
4000 divided by 100 = 40
It will take her 40 weeks to reach 4000
However, 4000-1600=2400
In another 16 weeks she'll get back to 4000
The total of weeks she'll need to save will be 56.
She won't have enough money in 55 weeks.
To find x, you divide both sides of the equation by 12.20. This would look like this:
12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
