Thank you for the opportunity to help you with your question!

volume of solid ball ( sphere) =  (4/3) *π r^3

                                                =  (4/3) *π  45^3

                                               = 121500 π    mm^3............................answer

                                               = 121500 * 3.14 mm^3

                                               = 381510    mm^3...............................answer


hope you understood..please message if you have any doubts...thank you

can you explain how you got the 121500

(4/3) *π r^3

= (4/3) *π  45^3

= (4/3) *π  *45*45*45

= (4/3) *π *91125

= (91125*4 / 3) π

= ( 364500 /3 ) π

= 121500 π
