Two solid sphere made up of same metal have weight 5920g and 740g respectively determine the radius of the larger sphere if the diameter of the small

sphere is 5cm.


Set proportions 
Large weight/Small weight = Large diameter/ Small diameter 

5920/740 = x/5 

Cross multiply 
740x = 5(5920) 
740x = 29600 

Divide both sides by 740 
740x/740 = 29600/740 
x = 40 cm
radius =20 cm

0 0 0
u hav taken x as a diameter.... so diameter is equal to 40...... then radius will b 20...
then answer will be 20
