Use the following formula to find the volume of a sphere
[tex]\boxed{V= \frac{4}{3} \times \pi \times r^{3}}[/tex]
plug in the numbers
[tex]V= \frac{4}{3} \times 3.14 \times 3^{3}[/tex]
[tex]V= \frac{4}{3} \times 3.14 \times 27[/tex]
[tex]V= \frac{4}{3} \times 84.78[/tex]
[tex]V=113.04[/tex]
The volume of the sphere is 113.04 yd³
