Answer:
The perimeter is 96.78 Hope this helps! :D
Explanation:
radius squared times pi is the diameter.
radius is 6
squared is a number times itself
6 squared is 6 times 6 which 36
pi is 3.14
36 times 3.14 is 113.04
since a 1/4 piece is missing, 113.04 divided by 4
that is 28.26
113.04 minus 28.26 is 84.78
the length and width of the slice missing is 6
6 plus 6 is 12
84.78 plus 12 is 96.78
