The radius of a wire is decreased to one-third. If volume remains the same, length will increase by ?

The radius of an iron rod decreased to one-fourth. If its volume remains constant , the length will becomes :

When a uniform wire of radius r is stretched by a 2kg weight, the increase in its length is 2.00 mm . If the radius of the wire is r//2 and other conditions remain the same, the increase in its length is

If the height of a cylinder is doubled and radius remains the same, then volume will be

When a uniform wire of radius r, is stretched by a 2 kg weight, the increase in its length is 2.00 mm. If the radius of the wire is R/2 and other conditions remaining the same, the increase in its length is

Suppose the height of a pyramid with a square base is decreased by p% and the lengths of the sides of its square base are increased by p% (where p>0). If the volume remains the same,then
