Let $$\triangle$$ be the area of the circumcircle of a right angled triangle ABC with $$\angle B$$ = 90°. Let $$\triangle_1 and \triangle_2$$ be areas of the two circle with diameters BC and BA respectively. Then

A

$$\triangle^2$$ = $$\triangle_1^2 + \triangle_2^2$$

B

$$\triangle = \triangle_1\triangle_2$$

C

$$\triangle = \triangle_1 + \triangle_2$$

D

$$\frac{\triangle_1}{\triangle_2} = \triangle$$
