Either enter an exact answer in terms of 7 or use 3.14 for I and round your final answer to the nearest hundredth.
units

Answer 1

Volume of the given sphere = 4.19 units³

Explanation:

Volume of a sphere is given by the expression,

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

Here, r = radius of the sphere

From the picture attached,

Radius of the sphere 'r' = 1 unit

Volume of the given sphere =
`(4)/(3)\pi (1)^3`

=
`(4)/(3)\pi`

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

= 4.187

≈ 4.19 units³
