Answer:
36π in³ ≈ 113.04 in³
Step-by-step explanation:
The formula of a volume of a sphere:
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
R - radius
We have r = 3in.
Substitute:
[tex]V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=4\pi(9)=36\pi\ in^3[/tex]
Use the approximation of number pi [tex]\pi\approx3.14[/tex]
[tex]V\approx36(3.14)=113.04\ in^3[/tex]
