Answer 2

Answer:

We know, all angles subtended by a diameter on it's semi-circular arc are right angles. So, all the semi-circular triangles are right-angled triangles standing on same base, 2r; but with varying height (maximum height being r). Therefore, the maximum area of the triangle = (1 / 2) * (2r) * (r) = (r^2).
