Question

Dosha is creating a new dessert that has two layers shaped like cones. The inner cone is frozen ice cream and has a diameter of 12 cm and a height of 6 cm. The outer layer is a thin wafer shell, like an upside-down ice cream cone, with a height of 15 cm and the same diameter as the inner layer. Dosha will inject a cream filling into the space.

What is the volume of the cream filling?
Use 3.14 to approximate pi and express your final answer in hundredths.

@TheSmartOne ?

Answer 6

Can you help?

Answer 7

Find the volume of the bigger cone.
Find the volume of the smaller cone.

Answer = Volume of bigger cone - Voulme of smaller cone

Answer 8

How do I do that? Like I don't know the formula :/

Answer 9

Volume of a cone = \(\Large\sf \frac{1}{3}\times \pi \times r^2\times h\)

Answer 10

What would the 1 third be for?

Answer 11

?

Answer 12

Well the formula has 1/3 in it.. Kinda hard to explain .-.

Answer 13

Okay so where would I place my numbers?

Answer 14

So first it tells us that:
h = 15
d= 12

Hint: \(\sf\Large\frac{d}{2}=r\)

So what is r?

Answer 15

6 right?

Answer 16

So I have 1/3*pi*6^2*15 right?

Answer 17

correct!

Answer 18

os is lagging so bad, sorry about the dalays >.<
