------------------------------------------------
amount of time it takes to fill a whirlpool tub is inversely proportional to the square of the radius of the pipe used to fill it.
-----------------------------------------------

t=k%2Fr%5E2


------------------------------------------
pipe of radius 2.5 inches can fill the tub in 7 ​minutes,
------------------------------------------

k=t%2Ar%5E2
k=7%2A%282.5%29%5E2
k=43.75
