Jason is a writer who gets paid a certain number of dollars per page, but 25 percent of the money he makes goes to taxes. suppose d(p) represents the number of dollars jason gets paid as a function of the number of pages he writes, and suppose t(p) represents the number of jason's dollars that go to taxes. if t(p)=500, what is the value of (d-t)(p)?

We are given that
d(p) represents the number of dollars jason gets paid
t(p) represents the number of Jason's dollars that go to taxes
t(p)=500
Then
d(p) = 500 / 0.25
d(p) = 2000

The value of 
(d-t)(p) = 2000 - 500 = 1500

If one draws this, it may be seen that the area of the small circle plus the area of the two rings equals the area of the large circle.

The area of the large circle is 144 pi cm^2, from pi*r^2

The area of each of the rings is equal to that of the small circle, so the area of all three (circle and two rings) is 144pi cm^2, and since the three are equal, the area of the small circle is 48 pi cm^2

That means 48 pi cm^2=pi* r^2

so r^2=48

r= sqrt (48) or 4 sqrt (3) cm or about 6.9 cm
