Question 282785: If four times the reciprocal of the circumference of a circle equals the diameter of the circle, then the area of the circle is:
a 1/π^2 b 1/π c 1 d π e π^2

4/pi x d = d then d^2 = 4/pi
d = 2/sqrt pi
so r = 1/sqrt pi
Area of circle is pi x r^2
so area is pi/pi = 1
The answer is (c)
