Answer-
Let the volume expansion be γ
Let the area expansion be β
Let the linear expansion be α
Now we know that γ=3α
β=2α
Also change in volume will be directly proportional to γ=3α
And change in radius will be proportional to α
So maximum percentage change will occur in volume and least in radius.
