Answer» Given:- a metallic solid sphere of radius 10. 5 cm is melted and recasted into smaller solid cones each of radius 3. 5 cm and height 3 cm. Let the number of small solid cones be n. ∴Volume of the sphere=n× Volume of each small solid cone=>n=Volume of the sphere/Volume of each small solid cone=>n=(4πr³/3)/(πr'²h/3)=(4×3.14×10.5³/3)/(3.14×3.5²×3/3)=126 ∴n=126 |
