The circumference is 37.68.
explanation:
formula of a circle: 2x3.14(pi)xradius
so we know that the diameter is 12. in order to find the circumference, we need the radius. to find radius with the given diameter, you divide the diameter by 2. 12/2=6.
using the formula for circumference, 2 x 3.14 x 6 = 37.68

A company has determined that when x hundred dulcimers are built, the average cost per dulcimer can be estimated by C(x)=0.2x^

damaskus [11]

Answer:

The minimum average cost per dulcimer is 150 and the minimum cost is $180.

Step-by-step explanation:

The given cost function is

$C(x)=0.2x^2-0.6x+2.250$

Differentiate the function C(x) with respect to x.

$C'(x)=0.2(2x)-0.6(1)+(0)$

$C'(x)=0.4x-0.6$

Equate C'(x)=0, to find the critical values.

$C'(x)=0$

$0.4x-0.6=0$

$0.4x=0.6$

Divide both sides by 0.4.

$x=\frac{0.6}{0.4}$

$x=1.5$

Differentiate the function C'(x) with respect to x.

$C''(x)=0.4(1)$

$C''(x)=0.4$

At x=1.5

$C''(1.5)=0.4$

The value of double derivative is positive. It means the function is minimum at x=1.5 hundred.

1.5 hundred = 150

Substitute x=1.5 in the given function to find the minimum average cost.

$C(1.5)=0.2(1.5)^2-0.6(1.5)+2.250$

$C(1.5)=1.8$

The minimum cost is 1.8 hundred dollars.

1.8 hundred dollars = $180

Therefore, the minimum average cost per dulcimer is 150 and the minimum cost is $180.
