Actually, yes, do you have some time to help me with another question? I just am worried because there is a time limit, I kind of am familiar with this one.

anonymous · Answer

The volume of a cone is three hundred cubic kilometers. If the radius of the base is 5 kilometers, what is the height of the cone? Use three point one four for pi. Show your work and round to the nearest tenth.

anonymous · Answer

I know the formula

mvpriest6 · Answer

what do u think it is and why

anonymous · Answer

v=1/3*3.14*r^2*h

anonymous · Answer

I think it would look like this: 1/3*3.14*25*h

anonymous · Answer

I know so far it is around 26 rounded

anonymous · Answer

so would I just subtract that from 300 and that's my answer?

mvpriest6 · Answer

ok what is a whole number that can become your answer

anonymous · Answer

274?

mvpriest6 · Answer

y

anonymous · Answer

I got it from subtracting 26 and 300

mvpriest6 · Answer

there is a number that you divide both sides on what is that number

anonymous · Answer

Waaait, not that's not right

mvpriest6 · Answer

its 254.34

anonymous · Answer

the height?

mvpriest6 · Answer

ok just round 3.53857042 to the nearest tenth

mvpriest6 · Answer

im talking about working the equation out

anonymous · Answer

I'm sorry, I'm confused, why do we do that?

mvpriest6 · Answer

just round it and that is your answer I skipped a lot because it takes awhile to explain

anonymous · Answer

I need to explain it though, can you give me a very short run down?

mvpriest6 · Answer

300=1/3(3.14)(9)exponent of 2h and it said pi. is 3.14 so we subsituted

mvpriest6 · Answer

first we multiply both sides by 3 to get rid of 1/3 ok

mvpriest6 · Answer

so what is that now

anonymous · Answer

Uum would it be 1 for 1/3 and 6 for 2?

mvpriest6 · Answer

we just cancelled out 1/3 so there's nothing for that and don't worry about six
