Do you know the formula for the volume of a sphere? @1497

anonymous · Answer

yes V=4/3pi^3

thesmartone · Answer

Are you sure you are not missing anything in that formula? @1497

anonymous · Answer

this is the formula

thesmartone · Answer

Correct. You were missing r in it.

You had pi^3 and r kind of disappeared lol

thesmartone · Answer

Do you know how r (radius) and diameter are related?

anonymous · Answer

no

thesmartone · Answer

So r is radius which is equal to 1/2 of the diameter.

So

r=.5 d

thesmartone · Answer

And they have given us d. But the formula we use has r and not d.

anonymous · Answer

I think it V=4/3pi9^3

thesmartone · Answer

Correct! If the diameter is 18 then the radius or r would be 9!

thesmartone · Answer

So we just do all the multiplication and leave $\pi$ alone and we will get out answer :)

thesmartone · Answer

So @1497 what do you get? :)

anonymous · Answer

I still didn't get my ans.
