Acone of volume 3770 is cut, parallel to its base, to give a smaller cone.

the volume of the smaller cone is half the volume of the original cone.
the smaller cone is melted down to make two different spheres.

•the ratio of the radii of these two spheres is 1: 2.

calculate the radius of the smaller sphere,
[the volume, v, of a sphere with radius r is v = nr.]

the answer should be 3.63 atleast to its nearest of decimal point difference

plaase show me the steps
