Question

the largest cone is curved out from one face of solid cube of side 21 cm .find the volume of the remainig solid pls ans I will give you a brainlist

Answer 1

side of cube= 21 cm
ATQ,
side of cube=diameter of largest cone curved out=21cm
and height of cone = 21/2cm
volume of cone= 1/3 x pi x r^2  x h
                       =2404.86cm3(by taking pi as 3.14)
volume of cube=21^3=9261 cm3
  so the volume of remaining solid = volume of cube-volume of cone
9261 cm3-2404.86 cm3=6856.14 cm3
