Answer» Answer:( i THINK that ratio of HEIGHT need to be calculated). The ratio of the height of the cines will be 2:5 Step-by-step explanation: Let the two radius be r1 and r2 And height will be h1 and h2 Since the ratio of volume is 1:10 THUS V1/V2=1/10 which will give r1^2 h1 / r2^2 h2 =1/10 ---(1) and r1 /r2 = 1/2 ( GIVEN ) thus putting in 1 gives h1/h2 = 2/5 Thus the required ratio of height will be 2/5 |
