Answer 2

Answer:

Step-by-step explanation:

Let ABC be the right angled triangle right angled at B.Let O be the centre of circle. O is the mid point of hypotenuse by geometry

OA= OB = OC = radius of the circumcircle = 3 cm

Hypotenuse AC= Diameter of circle =2 × radius of circumcircle=2×3=6 cm

Let be the perpendicular from B on AC

BM = 2 cm

area of right angle ∆= 1/2 ×B×H

=1/2×6×2 = 6cm^2
