Answer:

B

Step-by-step explanation:

The volume of a cone (V) is calculated as

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

Here V = 151 and r = diameter ÷ 2 = 12 ÷ 2 = 6 , then

\frac{1}{3} πr²h = 151 ( multiply both sides by 3 to clear the fraction )

πr²h = 453 , that is

3.14 × 6² × h = 453

3.14 × 36h = 453

113.04h = 453 ( divide both sides by 113.04 )

h  ≈ 4 m ( to the nearest metre ) → B
