V=At A confectioner is applying a sugar coating to some spherical candies. The given equation approximates V, the volume of coating in cubic millimeters, needed to create a t-millimeter thick coating on a candy with a surface area of A square millimeters. If 20π cubic millimeters of coating is needed to create a 0.2-millimeter thick coat on a spherical candy, what is the uncoated candy's radius in millimeters?
