Are you acually in middle school because this is algebra 2 and im learning this now in High school
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!
Answer:
a = 3.2
Step-by-step explanation:
2( -a - 8) + 7a = 0
-2a -16 + 7a = 0
5a - 16 = 0
5a = 16
a = 16/5
a = 3.2
