(a) To determine Calculate the volume of the solid generated by revolving the region about x axis. Explanation Given information: The solid generated by revolving the triangular region with vertices ( 0 , 0 ) , ( b , 0 ) , and ( 0 , h ) . Calculation: Sketch the triangular region with vertices ( 0 , 0 ) , ( b , 0 ) , and ( 0 , h ) as shown in Figure 1. Refer to Figure 1. Provide the equation of line as shown below. y = − h b x + h The outer radius R ( x ) = − h b x + h . The inner radius r ( x ) = 0 . The region lies between 0 to b. Calculate the volume of the solid about x axis using the formula: V = ∫ a b π ( [ R ( x ) ] 2 − [ r ( x ) ] 2 ) d x (1) Substitute − h b x + h for R ( x ) , 0 for r ( x ) , 0 for a , and b for b in Equation (1) (b) To determine Calculate the volume of the solid generated by revolving the region about y axis.

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
