Since, angle BOC is 180° , the angle CAB is 90°

Since, triangle ABC is RIGHT angled triangle, by USING Pythagoras THEOREM,

=> BC² = AB² + AC²

=> BC² = 49 + 576 = 625

=> BC = 25 cm

Diameter of circle is 25cm.

Radius of circle is 25/2 cm.

Area of triangle ABC = ½ × 24 × 7 = 84 cm²

Area of BOD :

$= > \frac{90}{360} \times 3.14 \times {(12.5)}^{2}$
