Hello!
Circular problems are the worst, am I right?
So as it says, A (Area) =

(Pi)

(Radius Squared.)
So Area = Pi times Radius Squared. The radius is the length from the center of a circle to any "edge" of the circle. So 1.5 feet is the radius.
1.5 Times 1.5 is 2.25. Pi is around 3.14. So 2.25 times 3.14. This is 7.065.
You're trying to find that red part. So you divide 7.065 by 4. It equals 1.76625.
Rounded to the nearest hundreth, it is 1.77.
Your answer is

I hope I helped!
Answer:

Step-by-step explanation:
In this problem we have a exponential equation of the form

where
y is the population of the city
x is the number of years
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=(1+r)
we have

substitute

For x=17 years
substitute the value of x in the exponential equation and solve for y


Answer:
(1.5, -13.5)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in our coordinates into the formula:
x = (17 - 14)/2
x = 3/2
y = (-11 - 16)/2
y = -27/2
72's factors is doubled the factors of 36.
