A publisher estimates the annual demand for a book to be 8000 copies, and built a warehouse to accommodate at most 8000 copies.

Illusion [34]

Answer: $1000

Step-by-step explanation:

Annual demand (D) = 8000

Cost per order (S) = $1000

Cost per unit to print = $8 per book

Storage cost = $2 per book per year

The minimum total cost can be found thus :

√(2 × D × S) / storage cost * cost per unit

√(2 × 8000 × 1000) / (2 * 8)

√ (16,000,000 / 16

√ (1,000,000

= 1000

Hence , minimum total cost $1000

Evaluate C= 2 A r, for r= 8.<br>C=10,<br>C = 16<br>C= 28.7<br>C= 16

USPshnik [31]

Answer: Second Option

$C = 16\pi$

Step-by-step explanation:

We are evaluating aarco lengths

The formula for the arc length is:

$C = 2\pi r$

We want to know what is the arc length for a radius of r = 8

Then we substitute r = 8 in the equation and solve

$C = 2 \pi * 8$

$C = 16\pi$

The correct answer is the second option
