You have to calculate the volume of a sphere with a diameter of 16ft.

To calculate the volume you have to apply the following formula:


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

Where "r" represents the radius of the sphere.

So, the first step is to determine the radius by dividing the diameter by 2:


\begin{gathered} r=(d)/(2) \\ r=(16)/(2) \\ r=8ft \end{gathered}

Using π =3, you can calculate the volume as follows:


\begin{gathered} V=(4)/(3)\cdot3\cdot8^3 \\ V=(4)/(3)\cdot3\cdot512 \\ V=2048 \end{gathered}

The volume of the sphere is 2048 ft³
