The above figure is a sphere of radius, r = 3cm,

The volume of a sphere, V, is given as,


\text{Volume of a Sphere V =}(4)/(3)\pi r^3

Substituting the radius into the formula,


\begin{gathered} Where, \\ r=3\operatorname{cm}, \\ \pi=3.14 \\ V=(4)/(3)*3.14*(3)^3=(4)/(3)*3.14*27=113.04\operatorname{cm}\approx113\operatorname{cm}^3(whole\text{ number)} \end{gathered}

Hence, the volume of the sphere is 113cm^3.
