We know that another name for a dome is half of a sphere,
lets check, if the diameter was 96" accross then the radius
has to be half that. Is it?
Let's try a similar dome,
38" accross, 19" high, taking the formula for surface area,

surface area = 4 π r2

we need to modify it because the dome will only be half of
the sphere.
So,
Surface Area of a dome = (1/2) 4 π r2 = 2 π r2
We know radius (height) and pi, now we just need to sub the
numbers in;
Surface Area of a dome = 2 π r2 = 2(3.1415...)(19)2
