The heights of two right circular cones are in the ratio 1 : 2 and the perimeters of their bases are in the ratio 3 : 4. Find the ratio of their volumes.	Choose the correct choice:
A) 1:14	B) 12:4	C) 9:6	D) 1:7	E) 9:32
Let the radii of their bases be r and R and their heights be h and 2h respectively.   Then,(2r/2R)=(3/4)  R=(4/3)r.    Ratio of volumes = (((1/3)r2h)/((1/3)(4/3r)2(2h)))=9: 32.   ANSW9:32R 9:32 9:32
