h=3r
v=512 π
512π = I/3πr 2h
512π = I/3πr 2x3r
512π = πr^3
r^3 = 512π/π=512
r =3 v512 = 8
RADIUS=8cm

Answer:
The correct answer of this question is 8cm
Step-by-step explanation:
Given - The height of the cone which is three times the radius of the base and it's volume of512pie cubic cm
Find - Find the radius of the base of the cone.
The height of the cone which is three times is h =3r
volume is = 512
512 = 2h
512 = 2× 3r
512 =
r = 3 ∨512 = 8
Radius is 8cm
