Question

The radius of a sphere is doubled the volume increased how many times

Answer 1

Answer:

Volume of a sphere is $\pi$$r^{3}$

if r increases to 2r. i.e. doubles,

then the volume of the sphere is:

$\pi$$(2r)^{3}$ = 8$\pi$$r^{3}$

therefore, if the radius doubles, the volume multiplies by 8

Answer 2

Answer:

Volume of Sphere will be 8 times when the radius is doubled

Step-by-step explanation:

Volume of a Sphere = 4/3πr³ Let it be S1

If the Radius is doubled, then the volume the volume = 4/3πR³, where R = 2r, be S2

S2 => 4/3π(2r)³

=> 4/3π8r³

=> 8 (4/3πr³)

= 8 S1

So the volume will be 8 times when the radius is doubled.
