The dispersed phase of a certain colloidal dispersion consists of spheres of diameter 1.0 10 2

Question:

The dispersed phase of a certain colloidal dispersion consists of spheres of diameter 1.0 × 10² nm.
(a) What are the volume (V = 4⁄3πr³) and surface area (A = 4πr²) of each sphere?
(b) How many spheres are required to give a total volume of 1.0 cm³? What is the total surface area of these spheres in square meters?
