Step-by-step explanation:
Answer:

Step-by-step explanation:
If r varies directly with the square of m and inversely as s,
then
where k is some constant
Given r = 12 when m = 6 and s = 4:
⇒
⇒ 
⇒ k = 
Therefore, substituting the found value of k into the original equation: 
Find r when m = 4 and s = 10:

⇒ 
⇒
