Answer 2

• the first answer is 192
  `\pi` in.²

• 2nd answer is 150
  `\pi` ft.²

Explanation:

1st question ➡ radius = 8 ÷ 2 = 4

Volume =
`\pi r^(2)` × height

=
`\pi` × 4² × 12

=
`\pi` × 192

= 192
`\pi` in.²

2nd question ➡ radius = 10 ÷ 2 = 5

Volume =
`\pi r^(2)` × height

=
`\pi` × 5² × 6

=
`\pi` × 150

= 150
`\pi` ft.²

Hope this helps!
