Question

Please help me with this Question

Answer 1

Total volume equals V1 - V2

`v = \pi {r}^(2) h`

`v = 12\pi {r1}^(2) - 12\pi {r2}^(2)`

where:

r1 = radius 1

r2 = radius 2

Explanation:

`r1 \\ v1 = 12\pi {3.5}^(2) \: is \: approx. \: 461.81 {cm}^(3)`

`r2 \\ v2 = 12\pi {3.3}^(2) \: is \: approx. \: 410.54 {cm}^(3)`

Total Volume v is

`461.81 - 410.54 = 51.27 {cm}^(3)`
