begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row d equals cell 20 blank cm end cell row straight r equals cell 1 half straight d end cell row blank equals cell 1 half cross times 20 end cell row blank equals cell 10 blank cm end cell end table end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell L subscript b o l a end subscript end cell equals cell 4 pi r squared end cell row blank equals cell 4 cross times 3 , 14 cross times 10 cross times 10 end cell row blank equals cell 1.256 blank cm squared end cell end table end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell V subscript b o l a end subscript end cell equals cell 4 over 3 blank pi r cubed end cell row blank equals cell 4 over 3 cross times 3 , 14 cross times 10 cross times 10 cross times 10 end cell row blank equals cell 4.186 , 67 blank cm cubed end cell end table end style

Jadi, luas bola Error converting from MathML to accessible text. dan volume bola Error converting from MathML to accessible text..
