Answer:

d = 289

Step-by-step explanation:

The circumference is given by

C = pi *d

907.46 = pi *d

Using 3.14 for pi

907.46 = 3.14 d

Divide each side by 3.14

907.46 /3.14= 3.14 d/3.14

289 = d

Answer & Step-by-step explanation:

$Circumference=d\pi$

In order to find the diameter, then we will have to rearrange the equation.

$d=\frac{Circumference}{\pi }$

Now, let's plug in our numbers to solve for the diameter, <em>d</em>. We will use 3.14 for pi.

$d=\frac{907.46}{3.14 }$

$d=289$

So, the diameter of the circle is 289 units.

Answer:

a) The reorder point necessary to provide a 95 percent service probability is 1557 units.

b) The Z value of 0.74 corresponds to 77% service probability.

Step-by-step explanation:

Average weekly demand (d) = 315 units

The standard deviation of weekly demand (\sigmad) = 90 units

Lead time (L) = 4 weeks

At 95% service level value of Z = 1.65

Reorder point = d x L + safety stock

$= d \times L + (Z \times \sigma d \times \sqrt L)\\\\= 315 x 4 + (1.65 x 90 x \sqrt 4)\\\\= 1260 +(1.65 x 90 x 2)\\\\= 1260 + 297\\\\= 1557 units$

b) Earlier the safety stock was 297 units(calculated in part a)

Now the safety stock is reduced to 55%.so,55% of 297 = 163.35 units

So the new safety stock = 297 - 163.35 = 133.65

$Safety stock = Z \times \sigma d \times \sqrt L\\133.65 = Z x 90 x 2\\133.65 = 180Z\\ Z = 133.65/180\\Z = 0.74$

The Z value of 0.74 corresponds to 77% service probability.
