The diameter is 2 so the radius is 1
The portion PQR is 3/4 of the diameter because the angle is 90 degrees
So 2/4=0.5*3=1.5

From the angle POR we can conclude that length of PQR is 3/4th of the perimeter of the circle.
But it is given that the diameter is 2 units and hence radius would be 1 unit.
So, length of PQR = 3/4*(2*pi*1) = 1.5*pi units
But it is given that the diameter is 2 units and hence radius would be 1 unit.
So, length of PQR = 3/4*(2*pi*1) = 1.5*pi units
