What is the volume of a sphere with a radius of 7mm
elena-14-01-66 [18.8K]
1)  The answer, in terms of  "π", is:
_________________________________
  "  (\frac{1372 mm^3}{3}) *  π    mm³ " .
___________________________________________________
2) The answer, using "3.14" for "π", is:
___________________________________________________
" 1436.0266666666666667  mm³ " ; round to: " 1436.027 mm³ " ; 

        or; write as: " 1436 \frac{2}{75}  mm³ " .
___________________________________________________
Explanation: 
____________________________________________
The formula for the volume, "V" of a sphere is:

V = \frac{4}{3} * π* r³ ;

in which "r" = radius = "7 mm" {given}.

We can solve using "3.14" for "π" ; or we can solve in terms of "π" ;
_________________________________________
1)  In terms of "π" :
_________________________________________
   V = \frac{4}{3} * π * r³ ;

      = \frac{4}{3} * π * (7 mm)³ ;

      = \frac{4}{3} * π * (7 * 7 * 7 * mm³) ;
 
      = \frac{4}{3} * π * (49 * 7 * mm³) ;

      = \frac{4}{3} * π * (343 mm³) ;

      = \frac{4* 343 mm^3}{3}) * π   mm³

      =  (\frac{1372 mm^3}{3}) *  π    mm³  ;

________________________________________________________
2)  Using "3.14" for "π" :
________________________________________________________
     V = \frac{4}{3} * π * r³ ; 

        = \frac{4}{3} * (3.14)* (7 mm)³ ;

        = \frac{4}{3} * (3.14) * (7 * 7 * 7 * mm³) ;

        = \frac{4}{3} * (3.14) * (49 * 7 * mm³) ;

        = \frac{4}{3} * (3.14) * (49 * 7 * mm³) ;

        = \frac{4}{3} * (3.14)  * (343 mm³) ;

        = { \frac{4}{3} }  * (3.14 * 343 mm³) ;

        = { \frac{4}{3} } *  (1077.02 mm³) ;

        = (4 * 1077.02 mm³) / 3 ; 

        = (4308.08 mm³) / 3 ; 
__________________________________________________________
        =  1436.0266666666666667  mm³ ;  round to: " 1436.027 mm³ " ;

        or; write as: " 1436 \frac{2}{75}  mm³ " .
