Question

Halp it has to do with volume, please and thank u.

Answer 1

Explanation:

Small cone:

r = 4 mm

h = 8 mm

Volume of small cone =
`(1)/(3)\pi r^(2)h`

`=(1)/(3)*\pi *4*4*8\\\\=(128)/(3)*\pi \ mm^(3)`

Bigger cone :

r = 8 mm

h = 16 mm

Volume of bigger cone =
`(1)/(3)*\pi *8*8*16`

`= (1024)/(3)\pi \ mm^(3)`

Volume of the space = Volume of bigger cone - volume of small cone

`= (1024)/(3)\pi-(128)/(3) \pi \\\\=(896)/(3)*\pi \\\\= (896)/(3)*3.14\\\\= 937.81 \ cm^(3)`
