Find the surface area of the full sphere [ A = 4 pi R2 ] and then take half of it.
You wind up with [ 2 pi R2 ] for the outside surface area of a half sphere, or
[ 4 pi R2 ] for the (inside + outside) surface area of the half sphere. (Since
the inside and outside are now both exposed to the weather, you probably
want to paint both surfaces.)

How do you figure out surface area for half sphere?
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
Why isn't the surface of a hemisphere not half the surface area of a sphere?
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
What is the surface area of a half-sphere with a radius of 10?
Surface area of half a sphere = 2*pi*radius2 Surface area = 200*pi = 628.3185307 square units.
What is the surface area of half a sphere with a radius of 4?
100.48
Formula for surface area of a spherical dome?
The surface area of a sphere is 4(3.14)R2where R is the radius of the sphere so the surface area of your dome is half of that. 2(314)R2

How do you find the surface area of a hemisphere?
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
What is the surface area of a half-sphere with a radius of 10?
Surface area of half a sphere = 2*pi*radius2 Surface area = 200*pi = 628.3185307 square units.
Suppose a rounded ball is cut into two equal pieces then what would be the formula to find the area of one-half piece of this ball?
Surface area of a sphere (a rounded ball) = 4*pi*radius2 Surface area of half a sphere = 2*pi*radius2

Find the total surface area of this half sphere with a radius of 10?
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
What is the total surface area of a half sphere with a radius of 10?
1500pi
What is half of the earths surface called?
A hemisphere is one half of the sphere that makes up Earth's surface.
What is the surface area of half a sphere without a lid?
It is: 2*pi*radius2 square units
How do you find the total surface area of a hemisphere whose diameter is 8 inches?
Calculate the radius (it is half the diameter).Use the formula for a sphere: area = 4 x pi x radius2.Since a hemisphere is half a sphere, divide this result by 2.Question:Do you mean the surface area to include the flat face of the hemisphere?If so then follow the above instructions and add pi*42 to your answer which will give you the complete surface area of the hemisphere.
