Answer:
see explanation
Step-by-step explanation:
A
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter ) , then
C = 3.14 × 8 ≈ 25.12 in
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 94.2 , then
2πr = 94.2 ( divide both sides by 2π )
r = 
= 15 cm
The mean is the sum of the given data divided by the number of the data
So we will add the data first
The sum of the times = 10 + 5 + 6 + 8 + 13 + 9 + 11 = 62
The number of students = 7
The mean is
Round it to the nearest tenth, then
The mean = 8.9
The mean travel time is 8.9

Answer:
44, 58, 74
Step-by-step explanation:
you add up by 2´s.
Which means, 4+4=8, 8+6=14, 14+8=22, 22+10=32
4,6,8,10,12,14,16
