Question

Q7. If the radius of the sphere is increased by 100%, the volume of the corresponding sphere is increased by [1]

Answer 1

Answer:

hey,

given:

the radius is increased by 100%

i.e radius becomes double.

we know, volume of sphere=4/3πr^3

therefore, new volume of sphere =4/3π(2r) ^3

=4/3π×8r^3

=8×4/3πr^3

which is 8 times the original volume. i. e volume increased by 700%.
