2. What are the shapes and dimensions of the cross sections that result from a slice perpendicular to the base, through the center, and a slice parallel to the base of a cylinder with a radius of 15 cm and a height of 19 cm?

The state of Nevada approximates the shape of a trapezoid with these dimensions for boundaries: 340 miles on the north, 515 miles on the east, 435 miles on the south and 225 miles on the west. If A and B are points located midway across the north and south boundaries, what is the approximate distance from A to B?

Find the perimeter of a segment of a circle whose boundaries are a chord measuring 24 mm millimetres and an arc of length 30 mm.

The oblique circular cone has an altitude and a diameter of base that are each of length 6 cm. The line segment joining the vertex to the center of the base is the axis of the cone. What is the length of the axis?
