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%2Ar%5E2 = 1600
r = sqrt%281600%2Fpi%29
r = 22.56758 ~ 22.6 ft
