At what rate is the plate’s area increasing when the radius is 50cm. 10. Approximate (a) 3 √ 1003 (b) (1 . 002) 100 11. A and B are walking on straight streets that meet at right angles. A approaches the interseciton from north at 2m/sec.; B moves away from the interseciton to east at 1m/sec. Let θ be the angle at B of the triangle OAB , where O denotes the intersection point. At what rate is θ changing when A is 10m away from O and B is 20m away from O . 2...
