Answer 1

come on @thebro55

You are STILL looking for someone else ot work out spherical volumes. This is at least th e6th question on th subject you have posted.

The formula for volume of a sphere has been posted in EVERY answer oyu got.

USE the formula, work out the 2 volumes (r= 18 and r=12)

then subtract one from the other to get 'how much more'

Answer 3

its 6cm

Answer 4

@puppylove<3123
That is the difference in radius

the difference in volumes requires you to use the formula

Vol = pi r^3 *4/3

Do that
first for r=18
THEN for r = 12

subtract the volumes to get the answer

Answer 5

thx @puppylove<3123 and @MrNood was that so hard

Answer 6

Answer 7

Answer 9

the trouble is that IF you had actually learnt anything from the previous questions then you would have KNOWN immediately that the answer is not 6

All the people who have helped you have wasted their time ,and you have wasted yours.

No-one can make you learn . But all I can say is you will get SOOOOOO much more form your life if you learn to love learning instead of shortcutting it.

Use the formula - trust your OWN judgement - you just trusted someone else who evidently had NO idea what he was talking about
