The ratio of heights  = ratio of the square roots of the areas because area is 2 dimensional and height is one dimensional.

so required ratio is  sqrt 40pi :   =  sqrt40:sqrt80 =  sqrt1: sqrt2 = sqrt (1/2) = 0.7071  to 4 significant figures

How do I solve my equation??
Law Incorporation [45]
If you would like to simplify this equation, the only thing that you can do is simplify the radical. 

\sqrt{18} = \sqrt{3 * 3 * 2}

Since 3 appears twice, we can factor it out of the radical. This gives us our answer of:

\frac{6 ± 3\sqrt{2}}{2}
