Answer 1

1538.60 ft³ and 6.50 cm

Explanation:

Volume of a cylinder = area of a circle x height

=
`\pi`r²×
`h`

1) Volume =
`\pi`r² x
`h`

= 3.14 x 7² x 10

= 1538.60 ft³ (to the nearest hundredth)

2) Volume =
`\pi`r² x
`h`

58.9849 = 3.14 x 1.7² x
`h`

58.9849 = 9.0746 x
`h`

`h` = 58.9849 ÷ 9.0746

= 6.50 cm (to the nearest hundredth)
