ANSWER

The volume of the sphere is 3,052.1 cubic meters

Step-by-step explanation

Given that

The radius of the sphere is 9m

pi = 3.14

To find the volume of the sphere, follow the steps below

Step 1: Write the formula for calculating the volume of the sphere


\text{ V = }(4)/(3)\pi r^3

Step 2; Substitute r = 9m into the above formula


\begin{gathered} \text{ V }=\text{ }(4)/(3)\text{ }*\text{ 3.14 }*\text{ 9}^3 \\ \\ \text{ V = }(4)/(3)\text{ }*\text{ 3.14 }*\text{ 9 }*9*9 \\ \\ \text{ V }=\text{ 4 }*\text{ 3.14}*\text{ 9 }*9\text{ }*\text{ 3} \\ \text{ V }=\text{ 3,052.1 m}^3 \end{gathered}

Hence, the volume of the sphere is 3,052.1 cubic meters
