Answer:
70%
Step-by-step explanation:
Total number of teenagers surveyed
12+20+38+20+10 = 100
Find the number of teenagers with 3 or fewer pairs of shoes
12+20+38 =70
P(3 or fewer) = teenagers with 3 or fewer/ total
= 70/100
= 70%
Circumference = 2 pi r
11304 = 2 x 22/7 x r
11304 x 7/2x22 =r = 1798.36
