Answer:
73.5
Step-by-step explanation:
circumference = 2πr , where r = radius
given radius = 11.7 so r = 11.7
C = 2πr
==> plug in r = 11.7
C = 2π(11.7)
==> multiply 2 and 11.7
C = 23.4π
==> multipl 23.4 and π
C = 73.5 ( rounded to the nearest tenth )
The microphone was $126.
You would multiply $38 by 6 which equals $228.
Then do $354-$228 which equals $126.
