Question

If the radius of a sphere becomes 3 times then it's volume will become.....? ​

Answer 1

Answer:

the new volume would increase by 27 times the original volume

Step-by-step explanation:

volume of sphere is 4/3πr^3

if radius becomes 3 times of original radius i.e.R=3r

then 4/3πR^3 =4/3π[3r]^3=27×4/3πr^3

Answer 2

Answer: mark me brainliest

the new volume would increase by 27 times the original volume

Step-by-step explanation:

volume of sphere is 4/3πr^3

if radius becomes 3 times of original radius i.e.R=3r

then 4/3πR^3 =4/3π[3r]^3=27×4/3πr^3
