Question

help me out in this!!!! ​

Answer 1

Answer:

Measure of angle QPR is 90 degrees and area of the shaded region is 77/2cm squrae

Step-by-step explanation: See ... according to degree measure theorem, angle QPR = half the measure of the central angle

Since QR is a line, central angle is 180 degrees.

Therefore, angle QPR is 90 degrees

Since QPR is a right angled triangle, use 1/2 * base * height for finding area of the triangle and subtract from semicircle's area
