Question

Sphere 6.2 in diameter

Answer 1

128.84 cubic inches.

Explanation:

We have that the volume of a sphere is given by the following equation:

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

The radius equals half the diameter, therefore we can calculate the radius as follows:

`\begin{gathered} r=(d)/(2)=(6.2)/(2) \\ r=3.1 \\ \text{replacing and we calculate the volume:} \\ V=(4)/(3)\cdot(22)/(7)\cdot3.1^3 \\ V=128.84 \end{gathered}`

The volume of the sphere with the diameter of 6.2 is 128.84 cubic inches.
