Step-by-step explanation:

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

C = 2πr

Most of the time, you can leave you answer in terms of pi (Ex: 2π), insteqad of actually multiplying it by pi.

Does this help?

Answer:

$\large \boxed{\text{Eight days}}$

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \text{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \text{2.5 mL }$

2. Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = 2.5

TOTAL = 162 mL

3. Calculate the number of doses

$\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}$

4. Calculate the number of days

$\text{Days} = \text{16.2 doses } \times \dfrac{\text{1 da}}{\text{2 doses}} = \textbf{8 da}\\\\\text{The solution will last for $\large \boxed{\textbf{eight days}}$}$
