Answer:

11.31

Step-by-step explanation:

<h3>given:</h3>

The diameter of the circle is 3.6 units.

Value of "a"

<h3>steps</h3>

Circumference of a circle in terms of radius:
Circumference = 2 · π · r = 2 · 3.14 · 1.8 = 11.31 (*)

In terms of diameter:

Circumference = π · d = 3.14 · 3.6 = 11.3 (*)

In terms of area:

Circumference C = √4·π·A = √4·π·10.18 = 11.31 (*)

Answer:

5,562 x $10^{-6}$

Step-by-step explanation:

Firts, we need to find the maximum recommended amount of bluefish per month. Since the FDA recommends <em>3 servings of 6.00 oz each</em>, the maximum amount would be:

the maximum amount of bluefish per month = $3 * 6.00 oz = 18.00 oz$

Since bluefish contains <em>0.309 ppm of mercury per 1x $10^{6}$ oz of fis</em>h, then:

0.309 oz mercury --------> 1x $10^{6}$ oz of fish

How many ( $y$ ) --------> 18.00 oz of fish

$y = \frac{18.00 oz of fish * 0.309 oz of mercury}{1 x 10^{6} oz of fish } = 0.000005562 = 5.562 x 10^{-6}$ oz mercury
