ANYONE PLS ASAPPPPPPP

Actually Welcome to the concept of surface areas and Volumes.

When the radius is 'r', we get as,

V = 4/3*(π)(r^3)

when the radius is tripled that is '3r' , we get as,

V' = 4/3 (π)(3r)^3

V' = 27*(4/3(π)(r^3))

V' = 27 V

hence the new volume, when radius is tripled, is 27 times greater than the old sphere.
