Answer:

(b) 10.5 in

Step-by-step explanation:

The formula for the volume of a cone is ...

V = 1/3πr²h . . . . . . for radius r and height h

Then the height is ...

h = 3V/(πr²)

Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...

h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in

The height of the cone is about 10.5 inches.
