Answer 5

yep :3

Answer 6

How many conical uns are there? :D

Answer 7

idk it doesn't say

Answer 8

Okay, I was complicating this question!

Just find the Volume of a conical urn
= pi * radius * radius * height.
= pi * 1.5 * 1.5 * 3 ft^3

Now find the volume of one urn! :D

Answer 9

i got 190.755 :3

Answer 10

3.14 * 2.25 * 3

That CANNOT be 190.755 :P

Answer 11

21.195 :p

Answer 12

I am sorry for that!

Colume of a cone = 1/3 * whatever your answer is.
= 1/3 * pi * r * r * h

Now solve it. You'll get the answer. :)

Answer 13

thanks got 6.3585 so im thinking B is the closest right?

Answer 14

Yes. :)
