Question

If radius of a sphere is doubled then how many times of its volume is increased

Answer 1

Answer:

New volume = 8 times earlier volume

Step-by-step explanation:

Original volume = 4/3 * 22/7 * r^3(i)

Now r'=2r

New Volume = 4/3 * 22/7 * (r')^3

New Volume = 4/3 * 22/7 * 8r^3 (ii)

Dividing i by ii-> Org. Vol/New Vol. = 1/8

New volume will become 8 times the earlier volume
