  • maths --plse help me.. -

    if answer is yes, then how can we prove the formula.

  • maths --plse help me.. -

    of course the answer is yes, assuming the formula is correct.

    Now the question is, what is the formula?

  • maths --plse help me.. -

    1/2((x/sinT)squared)*sinL*N
    T is 360 divided by n
    L is (180-T) over 2
    N is no of sides

    Just came up with this , still only checking it though
