Question 5

Three spherical balls of radii 1cm, 2cm and 3cm are melted to form a single spherical ball. In the process, the loss of material is 25%. The radius of the new ball is

Question 6

The diameter of a sphere is twice the diameter of another sphere. The surface area of the first sphere is equal to the volume of the second sphere. The magnitude of the radius of the first sphere is

Question 7
