The point B is at the centre of the circle. The pints P and Q are in the circumference of the circle. Calculate the area of the shaded sector. Take pi to be 3.142 in your working. Give your final answer to 1 dp.

24.7cm^2

Step-by-step explanation:

Line PQ = 5.413590865cm

BQ = 9cm

Angle BPQ =  

5.413590865² = 9² + 9² - 2 × 9 × 9 × cos(x)

29.30696605 = 81 + 81 - 162 × cos(x)  

29.30696605 = 162 - 162 × cos(x)

-132.693034 = -162 × cos(x)

cos(x) = 0.8190928022

x = 35.00591739˚

Area of sector = 24.7cm^2
