Chapter 6 Cross Sectional Volume 16.0 Students use definite integrals in problems involving area, velocity, acceleration, volume of a solid, area of a surface of revolution, length of a curve, and work. Cross section Plane cutting through object: a plane surface formed by cutting through an object at right angles to an axis, especially the longest axis. A cross section is the shape you get when cutting straight across an object.

Chapter 6 Cross Sectional Volume 16.0 Students use definite integrals in problems involving area, velocity, acceleration, volume of a solid, area of a surface of revolution, length of a curve, and work. 1.) Draw a cross section perpendicular to the x-axis. Write an expression that represents the length of that cross section. This is a “cross-section” of a 2D shape. A “cross-section” goes across the section. The width of each cross section (dx) is infinitely small (the cross section is a line) Saturday, February 23, 2019 ESLR -Tracy High Graduates will be Independent Learners Who Set realistic and challenging goals

Chapter 6 Cross Sectional Volume 16.0 Students use definite integrals in problems involving area, velocity, acceleration, volume of a solid, area of a surface of revolution, length of a curve, and work. Let R be the region in the first quadrant bounded by the graph of the horizontal line y = 6, the y-axis, and as shown in the figure. 3.) Region R is the base of a solid. For each x, where 0 ≤ x≤ 9, the cross section of the solid taken perpendicular to the x-axis is a square. Write, but do not evaluate, an integral expression that gives the volume of the solid.
