    (5pi/6) 10(5) = 250pi/6

    following so far, its converting the Sin(5π/6) into an exact ratio that gets me

    dont need to convert sin; it just theta/2 r^2

    the total area of a circle is 2pi/2 r^2 right?

    no this is a minor segment :/ need to use the A=(1/2)r^2(@-Sin@) (where @ = theta and in radians)

    yes but i need to use the above formula to figure out and converting the Sin part to exact ratios confuses the hell out of me

    the sin(5pi/6) = 1/2

    you take a 30 degree angle and look across it at the 1 and to the hyp of 2

    but doesn't 5pi/6 = 150 degrees? :Z

    yes; which has a reference angle of 30 degrees

    150 and 30 have the same sin
