Answer:

D

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = \frac{1}{3} πr²h ( r is the radius and h the height )

Here V = 226 and r = 12 ÷ 2 = 6 , then

\frac{1}{3}π × 6²h = 226 ( multiply both sides by 3 to clear the fraction )

3.14 × 36h = 678

113.04h = 678 ( divide both sides by 113.04 )

h = \frac{678}{113.04} ≈ 6 m ( to the nearest metre )
