SOLUTION: A is proportional to t^2 A is proportional to r^3 t=47 when r=0.25 find r when t=345 and pls tell the relationship between t and r

Question 971794: A is proportional to t^2
A is proportional to r^3
t=47 when r=0.25
find r when t=345
and pls tell the relationship between t and r
Answer by anand429(138) (Show Source): You can put this solution on YOUR website!
As per given proportionality conditions,
Let where k is any proportionality factor
When r=0.25, t=47
i.e
=> -(i)
So, when t=345, we have,
-(ii)
From eqn. (i) and (ii),
(Solve it)
And relatonship between t and r is given by initial condition
