What is the charge on the shell? Calculate the potential on the surface of the shell.

I need help with my physics homework…
“Consider a charged metallic spherical shell of a radius a = 1.75 cm. The potential at a distance of r = 6.0 cm from the center of the shell is measured to be 1.5 kV. What is the charge on the shell? Calculate the potential on the surface of the shell.”
I know the formula that must be used is V = kQ/r. Thus, V is given (1500 V), r is given (0.06 m), and k is a constant (8.99×10^9 N.m^2/C^2).
I’m a bit puzzled on how to solve the problem though…could someone help me understand solving for potential?
