We are to calculate the volume of a sphere of radius 2.9m
Volume of sphere is given as
[tex]V\text{ = }\frac{4}{3}\pi r^3[/tex]substituting the value of r
[tex]\begin{gathered} V\text{ = }\frac{4}{3}\text{ }\times\frac{22}{7}\times(2.9)^3 \\ V\text{ = }\frac{88}{21}\times24.389m^3 \\ V\text{ =}\frac{2146.232}{21}m^3 \\ V\text{ = 102.202}m^3 \\ V=102.2m^3\text{ (to the nearest tenth)} \end{gathered}[/tex]Therefore,
The volume of the sphere is 102.2 cubic meter
