In circle O, radius OQ measures 9 inches and arc PQ measures 6π inches. Circle O is shown. Line segments P O and Q O are radii with length of 9 inches. Angle P O Q is theta. What is the measure, in radians, of central angle POQ? StartFraction 2 pi Over 3 EndFraction radians StartFraction 3 pi Over 4 EndFraction centimeters StartFraction 4 pi Over 3 EndFraction radians StartFraction 3 pi Over 2 EndFraction radians

So for example, if the central angle was 90°, then the sector would have an area equal to one quarter of the whole circle. If you know the central angle. where: C is the central angle in degrees r is the radius of the circle of which the sector is part. π is Pi, approximately 3.142. This is the method used in the animation above.

Step-by-step explanation:

1. A tangent PQ at a point P of a circle of radius 5cm meets a line through the centre O at a Q so that OQ = 13cm. Find the length PQ. 2.From a point Q, the length of the tangent to a circle is 24cm and the distance of Q from the centre is 25cm.,find the radius of the circle.

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
