well
vol. of cylindrical glass=3.142 * (4)^2 * 6
=302 cm^3
vol. of cylindrical jar= 302 * 216
=65232cm^3

(V1/V2)=(r1/r2)^3
65232/302=(r1^3/4^3)
216 *64=r1^3
cube root (13824)=cube root (r1^3)
24 cm=r1
for height, it is the same method except for the value of r1 and r2 and it is switched by h1 and h2.
