The equation of a circle is represented as :

where,
- "h" represents x - coordinate of the center of circle
- "k" represents y - coordinate of the center of circle
- " r " represents Radius of the given circle
So, from above equation we get:
Therefore, Radius of the given circle measures 6 units.

Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
R = 14.1
Explanation:
r - 17.3 = -3.2
r = - 3.2 + 17.3
r = 14.1
