I have two problems that I am not sure about how to work out.
1. The distance traveled by a falling object is given by the formula d=4.9t^2, where d is in meters and t is in seconds. Solve the formula for t.
2.The volume of a right circular cone is given by the formula V=1/3(pi)r^2h. Solve the formula for r in terms of V and h.

1. First divide both sides of the equation by 4.9, giving you
0.20408 d = t^2
Then take the square root of both sides of the equation.
2. Multiply both sides by 3/(pi h), giving you
3 V/(pi*h) = r^2
Then take the square root of both sides.
