Hi Smiley Face !
______________________________________________________________
Volume of baseball = 13.39 inch³
volume of baseball =  \frac{4}{3}  \pi  r^{3}
                               
    ATQ            13.39     = \frac{4}{3}X \frac{22}{7} X r^3

                       13.39     = \frac{88}{21} Xr^3

      \frac{1339}{100} X \frac{21}{88} = r³

      \frac{28129}{8800}                    = r³

    03.196                                                           = r³

   ∛03.196                                                          = r³
   
     1.47         inch                                              = r
 
     2.94         inch
                                             = d

Hi Buddy !
_____________________________________________________________
Volume of ball = 13.39 inch ^3 
Volume of ball = 4/3 X pi x r^3 
ATQ 
4/3 X pi X r^3     =  13.39 
4/3 X 22/7 X r^3 =   13.39
                     r^3 = 13.39 x 7/22 x 3/4 
                     r^3 = 281.19/88
                     r^3 = 3.19 
                     r     = 1.47 inches
                     d    = 2  x 1.47 = 2.94 inches
