Identify the given radius.

The radius of the circle is given as $r = 3.5 \text{ cm}$.

The circumference $C$ of a circle is given by the formula:

We will use the approximation $\pi = \frac{22}{7}$.

The circumference of the circle is $\boxed{22 \text{ cm}}$.

Question 17:

The length $l = 15 \text{ cm}$, width $w = 10 \text{ cm}$, and height $h = 5 \text{ cm}$.

The volume $V$ of a cuboid is given by the formula:

Since $1 \text{ cm}^3 = 1 \text{ mL}$, the capacity in milliliters is:

The capacity of the cuboid is $\boxed{750 \text{ mL}}$.
