We are asked to determine the volume of a sphere. To do that we will use the following formula:


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

Where "r" is the radius.

We are given that the diameter is 8cm. We have that:


r=(D)/(2)

Where "D" is the diameter. This means that the radius is half the diameter. Substituting we get:


r=\frac{8\operatorname{cm}}{2}=4\operatorname{cm}

Now we substitute in the formula for the volume:


V=(4)/(3)\pi(4\operatorname{cm})^3

we will use:


\pi=3

Substituting we get:


V=(4)/(3)(3)(4\operatorname{cm})^3

Now we solve the operations:-


V=4(4\operatorname{cm})^3=256\operatorname{cm}^3

Therefore, the volume of the sphere is 256 cubic centimeters.
