A school distributes momentoes in the shape given below.
Here, \(\triangle PQR\) is right angled at \(P\). Also, \(PX\) \(=\) \(PY\) \(=\) 3 \(cm\) and \(XQ\) \(=\) \(YR\) \(=\) 19 \(cm\).
If \(XYRQ\) has to be painted in black, find the area to be painted black. [Use \(\pi\) \(=\) \(3.14\)]
Answer:
\(\text{Area of }\)\(\triangle PQR\) \(=\) \(cm^2\)
\(\text{Area of the sector }\)\(PXYP\) \(=\) \(cm^2\)
The area to be painted black \(cm^2\)
