The question is meaningless. A square is a plane figure which has "area" and not "volume" as in a sphere..
A perfect dome (1/2 of a sphere) has a surface area of 2piR2. This is because a sphere's surface area is 4piR2, and dividing that by 2 would simplify to 2piR2.
no, it is sphere is not a perfect circle. because sphere is 3dimensional figure and circle is 2 dimensional figure
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!
No. An area is always two-dimensional. It doesn't matter whether you are talking about the area of a square, a circle, an ellipse, or any other flat figure; or the surface are of a three-dimensional figure such as a cube or sphere.
It is incorrect to say that sphere has lateral area. First sphere do not have sides like other geometric figure. In fact a line or plane can intersect the surface of a sphere in just one point. Sphere has no lateral side. It is enough to say surface area of sphere than lateral surface area of the sphere.

Surface area concerns a 3-dimensional figure such as a cube or sphere. Area concerns a 2-dimensional figure such as a square or circle.

It is a sphere

Yes a sphere can be considered to be a curved plane 3 dimensional figure.

The sphere.
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
A circle is a plane figure. A 'circular' solid figure would be a sphere.
