Answer:
9
Explanation:
The height of a cone is dependent on its radius.
The height for a cone radius of 1 is 9.
Volume is the amount of space that is occupied by a three dimensional object.
The volume of a cone (V) is given by:V = (1/3)πr²
Where r is the radius and h is the height.
For a radius of 1:3π = (1/3)π*(1)² * hh = 9
