Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
Answer:
The amount of safety inventory of cell phones best buy should carry is $465.277
Step-by-step explanation:
Solution
We recall that:
The weekly demand for cell phones= 300 per week
The Standard Deviation = 200 per week
The lead time or number of weeks = 2 weeks (14 days)
Thus,
Z = 95%
= 1.645
Now,
The standard deviation of lead time = Standard deviation√ *√ lead time
Which is
= 200 * √ (2) =2.82.843
So,
The safety inventory = Z * Standard deviation of the lead time
= 1.645 * 2.82.843
$465.277
