Answer:
9.42
Step-by-step explanation:
The circumference of a circle is calculated using the following formula:
C=2πr (C: circumference, r : radius)
radius here is 6 and π is given as 3.14
2*(3.14)*6 = 18.84 now divide this by 2 to find the length of semicircle
18.84/2 = 9.42
twice the sum of a number and 3, means you need to add the number to 3 first, then multiply by 2.
The correct expression would be 2(n+3)
the first one is 37
the second one is 36
the third one is 27
sorry I dont know the way u put it makes no sense
a 9 degrees
so I'm not sure but if this is the right answer I think it's 9 so basically you do 14-5=9
