Answer :
This shape is 1/4 of a cylinder
Therefore its volume = volume of a cylinder / 4
[tex]\begin{gathered} The\text{volume }of\text{ cylinder }is \\ \pi\times r^2\times h \end{gathered}[/tex][tex]\begin{gathered} \text{volume of shape = }\frac{\pi\times r^2\times h}{4} \\ V\text{ = }\frac{\pi\times2^2\times10}{4} \end{gathered}[/tex]v = ( 40pi)/4
v = 10pi cubic meter
[tex]v\text{ = 10}\pi m^3[/tex]
