Answer:
44 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated using the formula
C = 2πr ← where r is the radius
here r = 7, hence
C = 2 ×π × 7 = 14π ≈ 44 cm ( to nearest whole number )
Answer:
They took 4,180 minutes total to complete the course.
Step-by-step explanation:
The average time is given by the sum of each individual time of the members divided by the number of members on the group. So if we want to know the total time they took to complete the course we need to take the average and multiply it by the number of people in the group. So we have:
total time = average*number of members = 110*38 = 4180 minutes
They took 4,180 minutes total to complete the course.
The mean of the number set is the average of the numbers
To find the average of the number set the numbers are to be added together and divided by the total amount of numbers in the set
12÷1=12
11÷2=5.5
10÷3=3.3
9÷4=2.25
8÷5=1.6
7÷6=1.16
