Answer: 57
Step-by-step explanation:
First you find the radius which has been given, it is 8.
You then plug it into area formula (pi r squared)
*pi = 3.14*
use a calculator and type in 3.14(8)^2
you will get 201 (rounded)
Second find the area of the square which is 12 times 12 equals 144
Now do 201-144= 57! Which is the shaded region :)
