finding electric potential using charge density

AMMax

1. The problem statement, all variables and given/known data

a 5 cm radius conducting sphere has a charge density of 2x10^-6 C/m^2 on its surface. Its electric potential, relative to the potential far away is?

2. Relevant equations

I used V= K(q/r)

3. The attempt at a solution

Using the above equation I got 1.12 x 10^4. This seems too easy. I think I am missing something here.
