Answer 2

Answer:

Let the initial volume of sphere be "r"¹ and the initial volume be " V"¹

So, the initial volume of sphere, V¹=4/3πr³.It is given that, the radius of sphere is increased by 100%

The new radius, r²=r¹+(100%of r¹) =2r¹

Now,

The new volume of the sphere,

V²=4/3πr²

V²=4/3π(2r¹) ³

V²=4/3π×(8×r¹) ³

V²=8×V¹

Thus,

The volume of corresponding sphere is increased by,

{(V²-V¹) /V¹}×100

{8(V¹-V¹) /V¹}×100

{7V¹/V¹}×100

7×100
