Ellie’s bird feeder is shaped like a cone with a height of 25 in. and a radius of 3 in. Packages of bird seed are cylindrical and come in different sizes.

What is the height of the package that has a radius of 5 in. and contains exactly enough bird seed to fill the feeder? Use 3.14 to approximate pi.

Do you know the formula for a volume of a cone?

anonymous · Answer

ya

anonymous · Answer

v= pie r2 h

anonymous · Answer

no that is the volume of a cylinder

anonymous · Answer

1/3

anonymous · Answer

i forgot that

anonymous · Answer

Good. Since the packet can completely fill the cone you will first need to compute the volume of the cone

anonymous · Answer

okey i got 235.5

anonymous · Answer

but it wont lett me the full answer

anonymous · Answer

now since it can completely fill the cone that means the two volumes are equal. So  all you have to do is solve the volume for a cylinder equation for h

lol thats not the answer Just the first step

lel

im confused 
O.o

anonymous · Answer

What is confusing you?

anonymous · Answer

the second part

plz :)

If i have 1 cup of water but the glass is a cylindrical shape and I pour the water into a cone shaped cup and it completely fills the cup. You can say both containers of a volume of 1 cup correct?

anonymous · Answer

In this case the problem is simply telling you that they have the same volume
