The average is 30 because 36+26+30+28=120 divided by 4 = 30
12 A . my guess would be to divide 2175 by 18 which would give you 120.83
11yd is the diameter and circumference is 2πr = 2π(d/2) = πd = 11π yd
Proportion if im not mistaken
is over of percent over 100
14 over 168 and x over 100 . 14 times 100 divided b 168 i believe .
