    Radian Measure 2

    Hi

    Three circles drawn with radius length 5 cm. Their centres are at the vertices of an equilateral triangle whose sides are of length 10 cm. Calculate the area between the circles.

    This is how I depict the question:



    Could someone please show me how to do this question? The answer's supposed to be 4.025 cm2.

    i wonder how..
    first, each circle has radius equal to 5 cm.. the centers form the "vertices" of an "equilateral triangle" with side length equal to 10cm..

    lets take 2 circles, if their centers form a segment equal to 10 cm, then the circles must be tangent to each other... take a look at it..
