Question

Given a sphere with a radius of 4 cm, find its volume to the nearest whole number.

Answer 1

`\begin{gathered} \text{ The volume of a sphere is given by the formula} \\ V=(4)/(3)\pi r^3,\text{ where r is the radius of the sphere, thus , the volume of the sphere is} \\ \\ V=(4)/(3)\pi(4)^3 \\ V=(4)/(3)\pi(4)^3 \\ V=(4)/(3)\cdot64\cdot\pi \\ V=(256)/(3)\pi \\ V\approx268\text{ cm}^3 \\ \end{gathered}`
