area of dish end
(2/3)*base*height
6(pi)l2, where l = length of side
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.
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 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 answer will depend on what information you have.
Calculating volume and surface area.
2(l*w)+2(w*h)+2(l*h)=surface area
(2/3)*base*height

6(pi)l2, where l = length of side
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
SA = 4 π r2 (SA is surface area = 4 (X) pi(3.142) (X) R(adius) squared
It depends on how many sides are part of the "opening".
A = 2 x pi x r (r + h)
