Answer 1

The Volume of a Sphere

The volume of a sphere of radius r can be calculated as:

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

The sphere in the figure has a radius of r = 12 cm. Calculate the volume:

`V=(4)/(3)\pi12^3`

Approximating the value of π = 3:

`V=(4)/(3)(3)12^3`

The value of 12 cubed is 12*12*12 = 1728. Substituting:

`\begin{gathered} V=(4)/(3)(3)(1728) \\ \text{Calculating:} \\ V=6912 \end{gathered}`

The volume of the sphere is 6912 cubic cm
