Question

(Oy By melting a lead sphere of diameter 12
cm three small spheres are formed. If the
ratio of the diameter of small spheres be
3:4:5 find the radius of each small sphere.
[W.B.M. 1988]​

Answer 1

π{(3x)3+(4x)3+(5x)3}

=43π(6)3

x3(27+64+125)=216

x3×216=216

x3=216216=1

x=1–√3=1

Radius of smallest sphere = 3x

=3×1=3cm
