Question

= ______units^3

please help (:

Answer 1

V =
`(4)/(3)`π units^3

Explanation:

The formula for the volume of a sphere is:

V = 4π
`(r^(3) )/(3)`

Now, substitute 1 for r because the radius is 1:

V = 4π
`(1^(3) )/(3)`

Next, simplify the fraction:

V =
`(1)/(3)`(4π)

Finally, multiply
`(1)/(3)` by 4π:

V =
`(4)/(3)`π
