if you don't have a Unit Circle, this is a good time to get one, you can find many online.
Check the picture below.
Answer:
197.77
Step-by-step explanation:
Area of circle: A=pi r^2
A= pi 9^2
A= 81 pi
only half of the circle so 40.5
Area of a Square: L x W
18 x 18 = 324
324 - 40.5pi = 197.77
World Bank's threshold for poverty is $1.25 per person per day.
For a family of four this gives:
Daily income = (number of people) * threshold
Daily income = 4 * $1.25
Daily income = $5
For a year this is:
Yearly income = (daily income) *365
Yearly income = $5 *365
Yearly income = $1825
