A lawn sprinkler sprays water in a circular pattern at a distance of 15 feet from the sprinkler head which rotates through the angle of `(5pi)/(3)` radians, as shown by the shaded area in the diagram above. What is the area of the lawn, to the nearest square foot, that recieves water from this sprinkler?

Jack waters his lawn with a sprinkler that sprays water in a circular pattern. The maximum reach of the sprinkler is 15 feet , and the sprinkler head rotates through an angle of 300^@ , as shown in the diagram below . The sprinkler head is represented at point O. To the nearest square foot , what is the area of the lawn (the shaded area ) that receives water from the sprinkler ?

Water from a sprinkler comes out with a constant velocity u in all the directions. What is the maximum area of the grassland that can be watered at any time?

A circular flower garden has an area of 314m^(2). A sprinkler at the centre of the garden can cover an area that has a radius of 12m. Will the sprinkler water th entire garden ?( Take p pi=3.14)

In the figure below, a highway rest area (at D) and radar stations (at A and B) lie on a level east-west line, A is 9,000 feet due west of D. An airplane (at C) is shown directly above the rest area, flying due west at a constant speed of 300 feet per secod and at a constant altitude of 12,000 feet. The airplane is located at a straight-line distance of 15,000 feet from the radar station at A and 13,000 feet from the radar station at B. Which of the following values is closest to the number of seconds it will take for the airplane to fly from C to the point directly above the radar station at A?

The distance between the eye and the feet of a boy is 1.5 m. He is standing on a flat ground and a vertical plane mirror M is placed at a distance of 1.2 m from the boy, with its lower edge at a height of 0.3 m from the ground. Now the mirror is tilted about is lower edge as shown in the Figure. Find maximum value of angle theta for which the image of feet remains visible to the boy. [Take sin 15^(@) = (1)/(4)]

A large mass M and a small mass m hang at the two ends of string that passes through a smooth tube as shown in fig. The mass m moves around in a circular path which lies in a horizantal plane. The length of the string from the mass m to the top of the tube is of length l and theta is the angle this length makes with the vertical, what should be the frequency of rotation of the mass m so that M remains stationary if M=16kg, m=4kg, l=1m and g=pi^(2)m//s^(2)
