Answer:

2:1

Explanation:

Circle P has radius 14 feet.

The circumference of this circle is given by:

$C=2 \pi \: r$

We plug in the radius to get:

$C=2\pi \: * 14 = 28\pi$

Circle Q has diameter 14 feet.

The circumference of this circle is given by

$C=\pi \: d$

We substitute the diameter d=14 to get,

$C=\pi \: * 14$

$C=14\pi$

The ratio of the circumference of P to the circumference of Q is

$28 \pi: 14\pi = 2:1$
