its 2 pie r squared
BUT you have to add back the base (a circle) which is pie r2
The original formula is 4 pie r squared
Your new formula is (2 pie r squared + pie r squared)

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.
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!
How to find the surface area of a half sphere?
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.)
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 total surface area of a half sphere with a radius of 10?
1500pi
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
What is the surface area of a sphere?
The formula for the surface area of a sphere is 4*pi*r2
Surface area of sphere?
Surface area of sphere is : A= 4*pie*r^2
Formula for area of a sphere?
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
