The formula for finding the area of a circle is A=pi(r^2). In this problem, you do 3.14 x 23^2.
3.14 x 23^2--->3.14 x 529--->1661.06 yards.

Answer:
Its the first option.
Step-by-step explanation:
y = 3x - 9 on the boundary.
Any points on this line must satisfy this equation.
Try (0, -9) and (3,0):-
-9 = 3(0) - 9 = -9 so the first point is on the boundary.
(3, 0):
0 = 3(3) - 9
= 9 -9 = 0 so this point is on the line also.
A = 5 is the correct answer <3
Greater than because 1/4 equals .25 and 2/5 equals .20
