we know that
the equation of the circle is of the form
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
so
the center is the point
the radius is
therefore
the answer is
The radius of the circle is equal to
When integrating, u-substitution is used to make things easier to work out. In u-substitution, the "u" is generally determined if its derivative is in the expression. That way when integrating with respect to "u", you can just replace the derivative of the u with "du" and easily integrate.
For this question, it would be easiest to let:
Let's take the derivative of u and see if we can work something out:
We have an x² in the integral expression, and therefore, it's valid for us to let u = 2x³. Thus, your answer is A.
