A = pi*r^2
so if you halve the diameter the new area will be
A' = pi*(1/2r)^2 = pi*1/4*r^2
= 1/4 * pi*r^2
So you get 1/4 the area.

From SumDude: No. It results in the radius.

No. It results in 1/4 of the previous area.
Let's say we have a circle with radius 10.
A=pir^2=pi*10^2=100pi which is about 314
Now let's half that radius to 5.
A=pir^2=pi*5^2=25pi which is about 78.5
314/78.5=4.03 which is basically 4. If we didn't round the area to about 78.5 and about 314,t it would have been 4 exactly.
