Answer» Let the radius of the spherical steel ball be 'X'Then the volume of the spherical steel ball=4/3πr³=4/3π(X)³Let the radius of the small spherical balls be 'x'Then, Volume=4/3π(x)³According to question:-4/3π(X)³=8[4/3πx³]4/3(X)³=32/3x³(X)³=8x³X=2xTherefore ratio- 1:2 check kar Raha tha sahi hai yaa fake mast hai |
