Answer:
The volume of the figure is 905 cubic units.
Step-by-step explanation:
Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.
volume of a sphere =
where r is the radius of the sphere.
Given that AB = 6, then the radius of the sphere = 6
volume of sphere = x
x
= x 216
= 905.14
volume of sphere = 905 cubic units
The volume of the figure is 905 cubic units.
