Answer:

16.8π cm or 52.78 cm

Explanation:

We are given the radius of one planet and the diameter of the other.

So, we have perimeter (circumference) of a circle is:

C = 2πr

where C is the circumference and r is the radius of the circle.

For the first planet with a radius of 16.8 cm, we can calculate its circumference as:

C1 = 2π(16.8) = 33.6π cm

For the second planet with a diameter of 16.8 cm, we can calculate its radius as half of the diameter:

r2 = d/2 = 16.8/2 = 8.4 cm

And then, we can calculate its circumference as:

C2 = 2π(8.4) = 16.8π cm

The difference between the perimeters of the two planets is:

C1 - C2 = (33.6π - 16.8π) cm

C1 - C2 = 16.8π cm

Therefore, the difference between the perimeters of the two planets is approximately 52.78cm, rounded to two decimal places.
