Ben and Kara are both looking at the top of a tower in the distance in the same line of sight, although Kara is 100 m ahead of Ben. Ben observes the tower at an angle 16 degrees of with the ground. If the top of the tower is 800 m from Kara, what is Kara’s angle of sight with the ground?

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
