Penjelasan dengan langkah-langkah:
v1 : v2 = 1 : 4
d1 : d2 = 4 : 5
r1 : r2 = (4/2) : (5/2)
r1 : r2 = 2 : 2,5
v1/v2 = (1/3 . π . r² . t)/(1/3 . π . r² . t)
1/4 = (2² . t1)/(2,5² . t2)
1/4 = 4t1/(6,25t2)
4t1 = 1
t1 = 1/4
6,25t2 = 4
t2 = 4/6,25
t2 = 16/25
t1/t2 = (1/4)/(16/25)
t1/t2 = 25/64
t1 : t2 = 25 : 64
