9. Find the area of the shaded region

If the length of \(XZ\)\(=\) 16 \(cm\) and \(YZ\) \(=\) 30 \(cm\), find the area of the shaded region and also the longest chord of the circle XY. (Hint: Take \(\pi = \frac{22}{7}\))

 

 

Answer:

 

(i) The length of XY \(=\)  \(cm\).

 

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

 

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