Question

What is the volume of a sphere, to the nearest cubic inch, if the radius is 7 inches? Use π = 3.14.

Answer 1

1436.03 in³

Explanation:

We can use the formula V =
`(4)/(3)`
`\pi`r³

Plug in 7 for r:

V =
`(4)/(3)`
`\pi`(7)³

Plug in 3.14 for pi:

V =
`(4)/(3)`(3.14)(343)

V = 1436.03 in³

Answer 2

`V=(4)/(3)\pi r^(2)`

=
`(4)/(3)` x
`\pi` x
`7^3`

= 1436.755040

Volume = 1436.755040
