Question

if the density of a sphere is reduced by 1 by 8 of its original value the radius of its year is dash times than its original radius assume that there is no change​

Answer 1

2

Explanation:

coz reduction in a density ,is the increase in volume.. like 1/8 in density reduction will increase the volume by 8 times.. this will take you to the equation as to show the 8 times volume to volume like

4/3*pi*r^3=8*4/3*pi*r^3

by solving this equation you will get the answer as follows

i hope it helps you
