As above, I would like to know the area of a standard-sized dartboard.
I think you should specify what you mean by the area. For all I know, a dartboard is a disc.
Area as in how many square feet there are in a standard dartboard.
Do you want to know the scoring area or the overall board?
How about both?
A disc has area [itex]\pi r^2[/itex], where r is the radius. I'm sure you can look up the radius of a standard-sized dartboard somewhere.
Separate names with a comma.
