Find the derivative of f(x).
f(x)=x3
write your answer as a constant times a power of x.

3x²

Step-by-step explanation:

(x³)

Apply the power rule: (x^a) = a * x^(a - 1):

3 * x^(3 - 1)

Simplify:

3x²

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
