Answer:

Diameter = 8

Step-by-step explanation:

Cone volume formula = (pi)*r^2*h/3

V = (12pi)*r^2*(9/3)

V = (12pi)*r^2*3

12/3 = 4

V =(pi)*4^2*h/3

4*2 = 8

The Diameter is 8

Answer:

2.2568m

Step-by-step explanation:

volume= 12 π cm³

or, 1/3 πr²h = 12π cm³

or, πr² × 9 = 12π ×3

or, r²= 36π/9π

or, r²= 4

or, r= 2

d = 2r = 2× 2= 4 cm
