Question

The volume of a sphere (U) varies as the cube of radius.​

Answer 1

Answer:

The volume of a sphere varies directly as the cube of its radius and its volume is 36 π cm

3

. Find the volume of the sphere, when the diameter is doubled.

ANSWER:-

Let the radius be r then

The volume of the given sphere is 36πcm

3

The volume of every sphere is,

V=4π

3

r

3

So we can equate the two volumes:

36π=4π

3

r

3

Multiply both sides by 3

r

3

=27

r=3 cm

Hence, this is the answer...
