9. Find the area of the shaded region

If the length of \(AC\)\(=\) 21 \(cm\) and \(BC\) \(=\) 28 \(cm\), find the area of the shaded region and also the longest chord of the circle \(AB\). (Hint: Take \(\pi = \frac{22}{7}\))

 

 

Answer:

 

(i) The length of \(AB\) \(=\)  \(cm\).

 

(ii) Area of the shaded region \(=\)  \(cm^{2}\).

 

[Note: Input the area value up to two decimal places.]
