12. You have to do the circumference of the circle and then divide it by 2.
10. 7^2 is not 14 it is 49 because 7*7 is 49.
What is the question asking?
The answer is 48.
<span>Out of 50 people, 4 had a mispriced item: 50 people - 4 mispriced
Out of 600 people, x will have a mispriced item: 600 people - x
Make a proportion:
50 : 4 = 600 : x
50 * x = 4 * 600
50x = 2400
x = 2400 / 50
x = 48</span>
<span>You first need to calculate the circumference as that will give you the distance in one revolution.
Then you multiply the answer you get by 8
Circumference = pi*diameter = 22pi 8 revolutions = 8*22*pi = 176pi
