The ratio A/r² would represent

which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is

r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
Technically this is a line segment, but since that is not an option. choose the answer “line”
the amount of money rick earned can be solve using the
formula:
F = P (1+ i)^n
Where F is the future money
P is the initial money
i is the interest rate
n is the time
F = 1000 ( 1 + 0.04)^10
F = $ 1,480.24
Sally
F = 1000 + (50)(10)
F = $ 1500
So the answer is D
