Answer:
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2

Answer:
I believe the answer is 8 because 8 can go in both 64 and 40.
Step-by-step explanation:
If you divide 64 by 8 then you get 8 and if you divide 40 by 5 you also get 8.
The slope is 1/3 because slope is rise over run so you go up one unit and go right three units.
I think the answer is 60/t = 5
