Well, the formula for the area of a circle is $$A = 2(\pi)r^2$$

lncognlto · Answer

And you are given the diameter, from which you can find the radius, and then you plug it into the formula, and voilà!

@Incognlto the formula is A=(π)r2

ok so correctly tell him now that how answers come out

anonymous · Answer

ok i got it .. sorry for the answer

lncognlto · Answer

No worries; I explained further up how to get the answer, but I'll say again for clarification, from the given diameter the radius can be obtained by dividing the diameter by two, and the result can be plugged into the given formula to obtain the area.
