Fofino [41]

Answer:

$x=0.04m$

Step-by-step explanation:

From the question we are told that:

Diameter $d=24cm$

Radius $r=24/2=>12cm$

Igniter distance $d_g=9cm$

Generally the equation for depth is mathematically given by

$r^2=4d_gx$

Therefore

$x=\frac{r^2}{4d_g}$

$x=\frac{12^2}{4*9}$

$x=4cm$

$x=0.04m$
