Two circles have the same radius 1 unit. If each circle passes through the centre of the other circle, what is the area common to the two circles? Area of two circles is 2pi. But how could I find the common area?

You'll need to make a sketch. You'll see that the common area can be divided into 6 parts of which there are 2 equilateral triangles and 4 equal segments. Can you try out to find the area now?

Can you try out to find the area now? So area of two equilateral triangles is Area of 4 segment = Therefore, enclosed area = Is this right?
