Benjamin is trying to find the height of a radio antenna on the roof of a local building. He stands at a horizontal distance of 25 meters from the building. The angle of
elevation from his eyes to the roof (point A) is 28°, and the angle of elevation from
his eyes to the top of the antenna (point B) is 40°. If his eyes are 1.52 meters from
the ground, find the height of the antenna (the distance from point A to point B).
Round your answer to the nearest meter if necessary.

Ahiking trail is 6 miles long. it has 4 exercise stations, spaced evenly along the trail. what is the distance between each exercise station?

The function f(x) is shown in this graph the function g(x)=6x

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)
