For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

Where:
r: It is the radius of the circle
According to the data we have:

Thus, the area of the cookie is:

We have 

We round:

Thus, the area of the cookie is 
Answer:

Answer:
B, 25 ft
Step-by-step explanation:
This can be modeled as a triangle. Let x be the height of the flagpole. From the picture, we can see that tan30 = x/43. x = 43tan30 = 25 ft.
Answer:
42mm
Step-by-step explanation:
Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.
5x+6x+8x = 159.6
19x = 159.6
x = 159.6 ÷ 19
x = 8.4
Shortest side of triangle (5x) = 8.4 × 5
= 42
