Base radius: $r=\sqrt{6.45}$

Step-by-step explanation:

Considering the cone is Right Circular Cone:

Volume of the cone = $\pi *r^2*\frac{h}{3}$

$r=radius \\\\h=height$

Given :

$Volume=54\\\\Height =8$

Putting in the formula:

$54=3.14*r^2*\frac{8}{3} \\\\ 54=\frac{25.12}{3} *r^2$

Multiply by '3' both sides:

$54*3=25.12*r^2\\\\162=25.12*r^2$

Divide by '25.12' both sides:

$r^2=\frac{162}{25.12}$

r^2=6.45

$r=\sqrt{6.45}$

So, the cone has base radius: $r=\sqrt{6.45}$
