n = 10
Thus the number is 10
Answer:
C) 16π ft
Step-by-step explanation:
Fencing is perimeter. The perimeter of a circle is the circumference.
The circumference of a circle is pi time diameter
C= pi*d
We know the diameter is 16
C = 16*pi ft
We will need 16 pi ft of fencing
A is not right. Half the cookie would have an angle of 180
B is not right. 4 pieces would have an angle of 288
C is correct. 360/5 is 72 degrees
D is not right. 2 pieces would have an angle of 144
E is correct 90<144 so a 90 degree angle would fit in 2 pieces
