Baseballs and softballs com in different sizes for different leagues. If the diameter of a baseball is 3 inches and a softball is 3.8 inches, find the difference between the volumes of the two balls. Use 3.14 for pie

4/3 pi r^3   is volume of a sphere      usin p = 3.14

 

softball (the larger of the two) = 4/3 pi (1.9)^3           (make sure you use RADIUS....the Q gives DIAMETER !!!)

        4/3  (3.14) (1.9)^3   in3   Use calculator to find volume of softball....

 

then find the volume of the BASEball the same way except  r = 1/2 d = 1.5 inches for baseball

    then find the difference between the two    ........    difference will be in3   (don't forget units in your answers !)
