Question 986266
A= pi sqrt (w/g)
i) if w=25 and g=16, Find A in terms of pi.
A = pi*sqrt(25/16)
A = (5/4)pi
-------------------------- 
ii) Sara now wants to use the formula to find w in a different situation. Rewrite the formula with w as the subject.
A = pi*sqrt(w/g)
A/pi = sqrt(w/g)
w/g = (A/pi)^2
w = g*(A/pi)^2
