    yes! I asked for that drawing, because my drawing it is impossible, since a traingle inscribed like mine has to be a right triangle

    here we can compute the area of our triangle, using the Eron's formula

    sorry, the area of a circle is: pi*radius^2=3.14*4*4=...? since the diameter is 8 inches, then radius= 4 inches
