Let's first find the volume of the whole cone, the first half of the expression \[\frac{1}{3} \pi r^2 h\] knowing the height and the radius of the cone, which choices can you keep?

snowflake0531:

And by the way you can look at this image, which I got from @extrinix we are looking at the whole cone right now, the height as 3, radius as 2

we can take out D I think

snowflake0531:

also another

stranger2:

and B

snowflake0531:

Okay and the sphere formula is \[\frac{ 4 }{ 3 } \pi r^3\]

snowflake0531:

btw remember that in the question, it gives diameter, so divide it by 2

snowflake0531:

After this, you should be able to get the answer

stranger2:

who was the radius again

stranger2:

well what

snowflake0531:

read the question

stranger2:

so its 2

snowflake0531:

... we're doing the sphere now
