If your choices are the following:

Not necessarily because cells them self don't actually contain cells
        
                    
             
        
        
        
Answer/Explanation:
Recall: 
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1
