Their are two intersecting circles. Circle 2's center sits on a point on the circumference of Circle 1.
Circle 2 has to overlap HALF of Circle 1's area.
Given that we know the diameter(/radius and circumference etc...) of Circle 1.
How do I work out the radius of Circle 2 (such that Circle 2 overlaps half the area of Circle 1)
Please any help would be apreciated.
Thanks in advance
