Answer:

She should use the formula
$C = \pi d$ to find a diameter of 16 inches.

Explanation:

The circunference of a circle is given by:

$C = 2\pi r$

In which r is the radius, which is half the diameter. So, it can also be given by the following formula:

$C = 2\pi (d)/(2) = \pi d$

In which d is the diameter.

Which formula should Maria use to help her find the diameter of the rug?

She should use this formula:

$C = \pi d$

Since the circunference is 50.24 inches, the diameter will be of:

$d = (C)/(\pi) = (50.24)/(\pi) = 16$
