ipn [44]

Answer:

Step-by-step explanation:The surface area of a sphere (the shape of a baseball) is given by the formula, SA = 4 (pi) r^2. Given the circumference of the circle, you can solve for the radius.

The formula for circumference is C = 2 x pi x r.

So input 9 for C and solve. 9 = 2 x pi x r.

You will get that r is equal to about 1.43 in.

Now put that r value into the surface area equation: SA = 4 (pi) 1.43^2

You will get a surface area equal to about 25.7 in^2.

Now multiply that number by the number of baseballs you need to cover, 100.

I'll let you do that step by yourself since it's simple algebra and you're smart enough to figure it out ;)

The least total cost method (LTC) lot-sizing technique calculates the order quantity by comparing the carrying cost and the setu

rewona [7]

Answer:

True

Step-by-step explanation:

The least total cost method is the method in which the total cost of the ordering cost and the total carrying cost is equal among various lot size available.

The order quantity should be choose when the total ordering cost and the total carrying cost equal to each other

The formula to compute the economic order quantity is shown below:

a. The computation of the economic order quantity is shown below:

$= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}$

It is always be expressed in units

The formula to compute the ordering cost is

$= \frac{Annual\ demand}{Economic\ order\ quantity}\times ordering\ cost\ per\ order$

And, the formula to compute the carrying cost is

$= \frac{Economic\ order\ quanity}{2}\times carrying\ cost\ per\ unit$

Hence, the given statement is true
