hello

to solve this question, we need to use the formula for volume of a sphere

$\begin{gathered} v=(4)/(3)\pi r^3 \\ v=\text{volume} \\ r=\text{radius} \end{gathered}$

from the image above, we can now find the radius of the sphere

$\begin{gathered} radius=\frac{\text{diameter}}{2} \\ d=18\operatorname{cm} \\ r=9\operatorname{cm} \end{gathered}$
$\begin{gathered} v=(4)/(3)\pi r^3 \\ v=(4)/(3)*3.14*9^3 \\ v=3052.08\operatorname{cm}^3 \end{gathered}$

from the calculations above, the volume of the sphere is equal to 3052.08cm^3
