Answer:

radius: 4.2 cm

circumference: 26.376 cm^2

area: 55.3896 cm^2

Step-by-step explanation:

radius is half the diameter so 8.4/2 = 4.2

circumference: C = (2)(pi)(r) ---> (2)(3.14)(4.2) --> 26.376

area: (pi)(r ^2) --> (3.14)(4.2^2) --> 55.3896

A certain food has a gluten ratio of 13mg per L of the food.what is the gluten ratio in micrograms per milliliter? PLEASE HELP M
AlekseyPX
Given:
The gluten ratio is 13 mg per L of food.

Note that
1 L = 1000 mL (milliliter)
1 mg = 10⁻³ g
1 μg = 10⁻⁶ g
Therefore
1 mg = 1000 μg

The gluten ratio is
(13  \frac{mg}{L} )*( 1000   \frac{\mu g}{mg} )*( \frac{1}{1000} \frac{L}{mL}  )=13 \frac{\mu g}{mL}

Answer:  The gluten ratio is 13 μg/mL
