Brogan Bradshaw · Answer 1

The new volume is 7^3 or 343 times the old volume

Step-by-step explanation:

The original sphere has a volume of

V = 4/3 pi r^3

The radius is multiplied by 7

The new volume is

V = 4/3 pi (7r) ^3

V = 4/3 pi (7) ^3 r^3

The new volume is 7^3 or 343 times the old volume
