Answer:
volume of the frustum --> v ≈ 28.27
Step-by-step explanation:
radius = 3 cm (because the small cone's radius would be half of what the large cone's radius is ---> 6/2 = 3)
height = 3 cm (because the question says the small cone's height is a quarter of the large one ---> quarter of 12 is 3)
Volume of a cone: πr^2h/3
v = π × r^2 × h/3
v = π × 3^2 × 3/3
v = π × 9 × 1
v = π × 9
v = 28.27
