Hi All
I need a formula to calculate the area of a trinagle, but theres a twist. The triangle as a curved face. Heres a picture of what I am talking about

I need to calculate the area using only the dimmensions specified on the drawing, A, B & C.
Many Thanks
Area of a circle = Pi*r^2.
Area of a secotor of a circle = 0.5*r^2*x
angle of sector = x = 2z
r = a = b
sin z = a/(0.5*c)
z = sin^-1(a/(0.5*c))
x = 2*(sin^-1(a/(0.5*c))) = angle of sector of circle
therefore:
Area of a secotor of a circle = 0.5*r^2*x
= 0.5*r^2*(2*(sin^-1(a/(0.5*
