    product rule is for finding the derivative of the product of two functions: \[(f(x) * g(x))' = f(x) * g'(x) + g(x) * f'(x)\]

    yes, and you can expand this concept to products of more than 2 functions...just remember to take the derivative of each product...so one derivative per term...

    \[(f(x) * g(x) * h(x))' = f(x) * h(x) *g'(x) + g(x) * h(x) * f'(x) + g(x) * f(x) *h'(x)\]

    I think by taking the change variation of the area as 2pi.r, we get what we are looking for by integrating.

    \[(uv)\prime = u \prime \times v +v \prime \times u \]
