Question
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.

d = 4.9t^2
get what you are solving for on one side and put everything else on the other side.
Do that by simple algebra.
Divide both sides by 4.9
d/4.9 = t^2
now take the square root of both sides.
sqrt(d/4.9) = square root (t^2)= +/-t.
You do the second one the same way.
