Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
Is there a formula for calculating the value of pi?
Yes. There are several, but some are "hard to use" or "hard to understand" and some other ones, particularly the "simple and easy" ones take a lot of work (a lot of steps) to derive "the next digit" in the sequence. Use the link to the Wikipedia article on calculating the value of pi and see what you think will work for you. If push comes to shove, there is software that will turn your PC into a pi computing machine. Need a link to the Wikipedia article? You got it.
What is the formula for calculating surface area of hemispherical dished end?
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.
