The area of the associated sector is
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The circumference of a circle is equal to

we have

substitute and solve for r


step 2
Find the area of the circle
we know that
The area of the circle is equal to

we have

substitute

step 3
Find the area of the associated sector
we know that
subtends the complete circle of area 
so
by proportion
Find the area of a sector with a central angle of 


and so on, and then, you graph those x,y coordinates

Factor square root of 32: 2^5/2.
Factor 4: 2^2

Cancel 2 1/2= 2 1/2.
2 1/2= square root of 2.
