Curved surface area of a hemisphere means only the bent part of it , i.e,the part which looks like half of a sphere.
Total surface area of a hemisphere is the circular top of a hemisphere + curved surface area of a hemisphere. So the formula goes like this:
Curved surface area of hemisphere= 2πr2
Total surface area of hemisphere= 2πr2 + πr2
= 3πr2
A sphere that has been sliced by a plane will have a circular base and a curved surface. In the special case that this plane goes through the centre of the sphere, the shape will be a hemisphere. in simple terms it would actually be a cone...
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
curved
A sphere has one continuous curved surface.
hemisphere
A hemisphere has no edges. It has one curved surface that smoothly transitions from the curved side to its base.
total curved surface area = 2*pie*r^2
A cylinder. Also, howsabout a hemisphere ?
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
A cone. A hemisphere.
hemisphere
A cylinder or a cone. Or a hemisphere.
3*pi*r2
The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
A sphere sliced by a plane, eg a hemisphere.
The difference between a "face" and a "flat surface" is found in what is being described by each term. A "face" refers either to the direction of a surface or to the simple fact of a surface as a surface. By contrast, a "flat surface" refers to the quality of the surface in question. Thus, one "face" of a building may be flat, smooth, curved, etc., while another may be similar or different.
