O is the centre of the circle, PQ is a chord. ∠POQ = 90°, area of shaded region (minor segment PRQ) is 114 cm², find the radius of the circle. (π = 3.14)
In the figure 7.46, if O is the centre of the circle, PQ is a chord. ∠POQ = 90°, area of shaded region is 114 cm², find the radius of the circle. (\(\pi=3.14\))
Figure: R is on the minor arc PQ; the shaded region is the minor segment between chord PQ and arc PRQ.
