Question

OMG HELP ME OUTTTTTTTTTTTTTTTTTT GRRRR

Answer 1

635.2 cm^3.

Explanation:

Volume of the cylinder = π r^2 h

= 3.14 * 4^2 * 5 = 251.2

Volume of the prism = 4 *8 * 12

= 384

Total volume = 384 + 251.2

Answer 2

Volume of the cylinder:

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

`v = 3.14 * {4}^(2) * 5`

`v = 251.2 \: {cm}^(3)`

Volume of the rectangular prism:

`v = lwh`

`v = 12 * 8 * 4`

`v = 384 \: {cm}^(3)`

Total volume:

`v = 251.2 + 384`

`v = 635.2 \: {cm}^(3)`
