Question 730895
A hemispheric dome is needed to cover a circular region having an area
 of 1600 square feet.
 What will be the height of this dome?
 Answer to the nearest tenth of a foot. 
:
Find the radius of the circular region, this is also the height of the
hemispheric dome
{{{pi*r^2}}} = 1600
r = {{{sqrt(1600/pi)}}}
r = 22.56758 ~ 22.6 ft
