The diagram shows a sector OAB of a circle, centre O and radius10 cm. Angle AOB is theta radians.

The point C lies on OB and iss such that AC is perpendicular to OB. The region R is bounded by the arc AB and by the lines AC and CB. The area of R is 22cm^2

1. show that theta=0.44+sin(theta)cos(theta)

2.Show that theta lies between 0.9 and 1.0
