Sphere
2.e. What is the formula for volume for this shape?
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
2.f. What is the volume of the figure?
The volume of the figure is 972π cm³
Step-by-step explanation:
2.f. What is the volume of the figure?
According with the figure, we have the radius r=9 cm. Replacing this value in the formula of the volume:
[tex]V=\frac{4}{3}\pi (9 cm)^{3}\\ V=\frac{4}{3}\pi (729 cm^{3})\\ V=4\pi (243cm^{3})\\ V=972\pi cm^{3}[/tex]
