The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.

The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
The answer will depend on what information you have.

calculating surface area
6(pi)l2, where l = length of side
2(l*w)+2(w*h)+2(l*h)=surface area
It depends on how many sides are part of the "opening".
A = 2 x pi x r (r + h)
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
