It whould be -1.5 for and 0.5
6% of $1,600 is = 96 if you multiple it with 180 : 96 × 180 = 17,280
The answer is C wnmdkdkdkdkdkdkdkdkdkdkd
18.84
Since the formula of circumference is C = 2 pi r or C = pi times diameter, you can conclude that the circumference is 18.84.
Assuming that pi is 3.14 in this case rather than the full pi or just in terms of pi.
Hope this helps!
